Hi Ansible folks, I get an “IOError: [Errno 11] Resource temporarily unavailable” error whenever I run a playbook with fork \> 1. Just wondering if anyone has seen this problem before or has trouble-shooting advice. Python 2.7.3 and Python 2.7.5 Ansible 1.1 Ubuntu 12.04 LTS Console output below… Cheers, Kyle PLAY [all] \*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\* TASK: [Setup passwordless ssh from master to workers] \*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\* 11 Traceback (most recent call last): File “./cli.py”, line 60, in main(sys.argv) File “./cli.py”, line 30, in main cluster.Resize(num\_instances) File “/home/ubuntu/git/iwct/build/snap/cirrus/cluster/mapr.py”, line 90, in Resize self.\_\_AddWorkers(num\_to\_add) File “/home/ubuntu/git/iwct/build/snap/cirrus/cluster/mapr.py”, line 505, in \_\_AddWorkers self.\_\_ConfigureWorkers(new\_worker\_instances) File “/home/ubuntu/git/iwct/build/snap/cirrus/cluster/mapr.py”, line 714, in \_\_ConfigureWorkers CHECK(util.RunPlaybookOnHosts(self.playbooks\_path + ‘/worker.yml’, hostnames, self.ssh\_key, extra\_vars)) File “/home/ubuntu/git/iwct/build/snap/cirrus/util.py”, line 84, in RunPlaybookOnHosts results = pb.run() File “/home/ubuntu/git/iwct/build/snap/ansible/playbook/ **init**.py”, line 222, in run if not self.\_run\_play(play): File “/home/ubuntu/git/iwct/build/snap/ansible/playbook/ **init**.py”, line 438, in \_run\_play if not self.\_run\_task(play, task, False): File “/home/ubuntu/git/iwct/build/snap/ansible/playbook/ **init**.py”, line 303, in \_run\_task results = self.\_run\_task\_internal(task) File “/home/ubuntu/git/iwct/build/snap/ansible/playbook/ **init**.py”, line 277, in \_run\_task\_internal results = runner.run() File “/home/ubuntu/git/iwct/build/snap/ansible/runner/ **init**.py”, line 660, in run results = self.\_parallel\_exec(hosts) File “/home/ubuntu/git/iwct/build/snap/ansible/runner/ **init**.py”, line 573, in \_parallel\_exec job\_queue = manager.Queue() File “/usr/lib/python2.7/multiprocessing/managers.py”, line 667, in temp token, exp = self.\_create(typeid, \*args, \*\*kwds) File “/usr/lib/python2.7/multiprocessing/managers.py”, line 565, in \_create conn = self.\_Client(self.\_address, authkey=self.\_authkey) File “/usr/lib/python2.7/multiprocessing/connection.py”, line 175, in Client answer\_challenge(c, authkey) File “/usr/lib/python2.7/multiprocessing/connection.py”, line 413, in answer\_challenge message = connection.recv\_bytes(256) # reject large message IOError: [Errno 11] Resource temporarily unavailable \*\*\* Aborted at 1371088581 (unix time) try “date -d @1371088581” if you are using GNU date \*\*\* PC: @ 0x7f3a63db6313 (unknown) \*\*\* SIGTERM (@0x3e800005710) received by PID 22554 (TID 0x7f3a65406700) from PID 22288; stack trace: \*\*\* @ 0x7f3a64fefcb0 (unknown) @ 0x7f3a63db6313 (unknown) @ 0x5560a1 (unknown) @ 0x49890a (unknown) @ 0x498602 (unknown) @ 0x498602 (unknown) @ 0x498602 (unknown) @ 0x498602 (unknown) @ 0x49f1c0 (unknown) @ 0x4a8a92 (unknown) @ 0x4e9f36 (unknown) @ 0x499bc0 (unknown) @ 0x498602 (unknown) @ 0x498602 (unknown) @ 0x49f1c0 (unknown) @ 0x4a8960 (unknown) @ 0x4e9f36 (unknown) @ 0x4ec11a (unknown) @ 0x4e9f36 (unknown) @ 0x4eb39e (unknown) @ 0x4db6a6 (unknown) @ 0x4e9f36 (unknown) @ 0x49846a (unknown) @ 0x498602 (unknown) @ 0x49f1c0 (unknown) @ 0x4983b8 (unknown) @ 0x498602 (unknown) @ 0x498602 (unknown) @ 0x498602 (unknown) @ 0x498602 (unknown) @ 0x498602 (unknown) @ 0x498602 (unknown) ---

check dmesg, that is normal when you run out of OS resources (# of open files, buffers, ram, etc). ---

Hi Brian, Thanks for the suggestion… I saw nothing posted to dmesg after I run the script that crashes. The script uses very little ram, and file and process/thread limits are set high enough… (ulimit -Hn → 64000, ulimit -Hu → 55457). Not sure what resource it ran out of… Taking the error message at it’s word that it is “temporary”, I wrapped the call to the multiprocessing manager Queue constructor\*\*\* in a retry loop… The exception gets raised only on the first attempt, and always succeeds on the second attempt. \*\*\*File “/home/ubuntu/git/iwct/build/snap/ansible/runner/ **init**.py”, line 573, in \_parallel\_exec job\_queue = manager.Queue() before hack: job\_queue = manager.Queue() after hack: job\_queue = None while not job\_queue: try: job\_queue = manager.Queue() except: pass print ‘error… will retry…’ time.sleep(2) My script doesn’t crash now… I don’t understand the root cause of the problem. Has anyone else seen such an issue? I’ve seen a few reports of this error outside of ansible when using multiprocessing and sockets… Anyone else had this problem before? -Kyle ---

An execeedingly large number of folks are running LTS and I’ve never seen this reported. Seems like you are using the API instead of /usr/bin/ansible-\* though, so not sure what may be going on. ---

Michael, Thanks for the reply… I bet you are right… I’ve probably done something in my code before the ansible API gets called that causes the crash. I use the multiprocessing and paramiko modules in other parts of my code before calling the ansible API, perhaps there is an interaction. PS: I’m converting a bunch of my custom python scripts for launching MapR hadoop clusters on EC2 to ansible playbooks… I’m very pleased with the results (much shorter and easier to maintain). Thanks for making such a well designed tool! Cheers, Kyle ---

I think that is a network error, not a system resource error. IE the resource in question is a network host or service. ---

Did anybody find any solution to this error. I am having the same issue not. I am using Ansible 1.7.2 with Eucalyptus cloud. msg: Instance creation failed =\> InternalFailure: Not enough resources: no cluster controller is currently available to run instances. Thanks, Sp ---

I am too getting this error and could not find a way to fix it … I am using ubuntu 14.04 and using the python api to call the playbook.run() This used to work when i used to invoke my code from apache. But now i am trying to call using a simple python command like “python consumer.py” Dont know if i need to specify anything else ? 2015-01-31 00:26:04,933 - root - ERROR - Error in executing playbook[Errno 11] Resource temporarily unavailable Traceback (most recent call last): File “/opt/stack/venv/local/lib/python2.7/site-packages/attis-1.0.0a1-py2.7.egg/attis/engine/contentprocessor.py”, line 100, in runPlaybook pb.run() File “/opt/stack/venv/local/lib/python2.7/site-packages/ansible-1.8.2-py2.7.egg/ansible/playbook/ **init**.py”, line 347, in run if not self.\_run\_play(play): File “/opt/stack/venv/local/lib/python2.7/site-packages/ansible-1.8.2-py2.7.egg/ansible/playbook/ **init**.py”, line 674, in \_run\_play self.\_do\_setup\_step(play) File “/opt/stack/venv/local/lib/python2.7/site-packages/ansible-1.8.2-py2.7.egg/ansible/playbook/ **init**.py”, line 619, in \_do\_setup\_step accelerate\_port=play.accelerate\_port, File “/opt/stack/venv/local/lib/python2.7/site-packages/ansible-1.8.2-py2.7.egg/ansible/runner/ **init**.py”, line 1458, in run results = self.\_parallel\_exec(hosts) File “/opt/stack/venv/local/lib/python2.7/site-packages/ansible-1.8.2-py2.7.egg/ansible/runner/ **init**.py”, line 1349, in \_parallel\_exec job\_queue = manager.Queue() File “/usr/lib/python2.7/multiprocessing/managers.py”, line 667, in temp token, exp = self.\_create(typeid, \*args, \*\*kwds) File “/usr/lib/python2.7/multiprocessing/managers.py”, line 565, in \_create conn = self.\_Client(self.\_address, authkey=self.\_authkey) File “/usr/lib/python2.7/multiprocessing/connection.py”, line 175, in Client answer\_challenge(c, authkey) File “/usr/lib/python2.7/multiprocessing/connection.py”, line 428, in answer\_challenge message = connection.recv\_bytes(256) # reject large message IOError: [Errno 11] Resource temporarily unavailable ---

OK, so i did a couple of tests. I ran the ansible api call from a regular python file like this python rough.py What rough.py does is simply call the python api. This works perfectly fine. Now why it was not working is because i has a oslo-messaging listener and then i passed the execution to the python api. Some how these 2 dont work together. i dont know if this is related or not [http://stackoverflow.com/questions/14736766/why-does-gevent-socket-break-multiprocessing-connections-auth](http://stackoverflow.com/questions/14736766/why-does-gevent-socket-break-multiprocessing-connections-auth) Question is is there any work around ?
