Getting very high load after latest changes

[Spacedust]

I got load with spikes like 80.00 and 90.00 on Intel(R) Core(TM) i7-4770 CPU @ 3.40GHz, 32 GB DDR3 1600 MHz, 2x 240 GB SSD RAID1, 2x 3 TB HDD RAID1.

How to identify scripts on php-fpm ? It's all the same name, only user is changing...

[Spacedust]

Example:

php-fpm[9194]: segfault at 7ffff5e69f90 ip 0000000000584ffa sp 00007ffff5e69f60 error 6 in php-fpm[400000+34f000]
