10 years ago You can use the master branch for naemon and nagios 4 now, i am going to remove the nagios4 branch, it was just a test. There is the nagios3 branch for old bug fix releases and the master branch for everything new.
I found that the naemon and nagios 4 cores now expect the check's output to have unescaped newlines. In the core, the last parameter to parse_check_output was changed from TRUE to FALSE -- which says to unescape newlines -- in handle_async_host_check_result and handle_async_host_check_result. Checks that are handled by the core workers don't escape the output's newlines like they were in nagios 3. Since the outputs coming from mod_gearman were still escaping the newlines, the output was not being parsed into the short, long, and perf outputs correctly. ex. [1401404189.001360] [016.1] [pid=31301] \ Handling async check result for host 'child1' from 'Mod-Gearman Worker @ naemon'... [1401404189.001369] [016.2] [pid=31301] Check Type: Active [1401404189.001378] [016.2] [pid=31301] Check Options: 0 [1401404189.001444] [016.2] [pid=31301] Scheduled Check?: Yes [1401404189.001453] [016.2] [pid=31301] Reschedule Check?: Yes [1401404189.001461] [016.2] [pid=31301] Exited OK?: Yes [1401404189.001469] [016.2] [pid=31301] Exec Time: 0.009 [1401404189.001481] [016.2] [pid=31301] Latency: 0.731 [1401404189.001492] [016.2] [pid=31301] Return Status: 0 [1401404189.001500] [016.2] [pid=31301] Output: Short Output\nLong Ouput\n | stuff=22mb;\n [1401404189.001514] [016.2] [pid=31301] Parsing check output...

To solve this, I pulled the replace_str function from the master branch to unescape the newlines in the output before giving it to the core. With the patch, the output is now correctly parsed:
