I would breakout the Linux perf command for something like this. Run it like this: perf record -p <pid_of_a_php-fpm_process> -g Let that run for some arbitrary amount of time. Start with 10 seconds, or so. Then: perf report -n That should give you a nice report of what your php-fpm process did for those 10 seconds. Now do the same thing when you see the problem and compare the reports. -Rasmus
