I have the following in my playbook. (As a side note, I am unsure of my syntax under “with\_items”. I have tried multiple variations, but I always get the same error. I just need another set of eyes to point out my problem):

`  
43 - name: Set tuning parameters in sysctl.conf  
44 lineinfile:  
45 path: /etc/sysctl.conf  
46 state: present  
47 line: “{{item.replace\_with}}”  
48 regexp: “{{item.regex}}”  
49 with\_items:  
50 - { replace\_with: ‘net.core.netdev\_max\_backlog = {{backlog\_value}}’,  
51 regexp: ‘^net._netdev\_max\_backlog._’ }  
52 - { replace\_with: ‘net.core.rmem\_max = {{bdp|int}}’,  
53 regexp: ‘^net._core.rmem\_max.’ }  
54 - { replace\_with: ‘net.core.wmem\_max = {{bdp|int}}’,  
55 regexp: ‘^net.core.wmem\_max.’ }  
56 - { replace\_with: ‘net.ipv4.tcp\_moderate\_rcvbuf = 1’,  
57 regexp: '^net.ipv4.tcp\_moderate\_rcvbuf.’ }  
58 - { replace\_with: ‘net.ipv4.tcp\_rmem = 4096 87380 {{bdp|int}}’,  
59 regexp: '^net.ipv4.tcp\_rmem._’ }  
60 - { replace\_with: ‘net.ipv4.tcp\_wmem = 4096 87380 {{bdp|int}}’,  
61 regexp: ‘^net.ipv4.tcp\_wmem.\*’ }  
62 #notify: sysctl\_trigger

`

I get the following error. You can see from the output that “bdp|int” is populated, as is “backlog\_value”. I don’t know what it is bombing on.

I found my problem. I put regex instead of regexp on line 48… It was a syntax issue
