Boonex Dolphin -> WordPress Migration – High CPU, PHP Defunct Process, and more
-
Ok here is one I am dying for help on.
I have a fairly high traffic site that was built on Boonex Dolphin. I have split up the site, and built 3 different WordPress installations (using the same DB). My CPU load has skyrocketed (usually under 1 according to top, it hovers all over the place, going 6, 10, and even higher. Sometimes, 60+ with tons of php processes. I am also seeing a ton of php defunct processes.
I have tried hard to tweak settings, but nothing seems to work. Here is the my.cnf:
[mysqld] max_allowed_packet=268435456 query_cache_size = 512M query_cache_limit = 4M tmp_table_size = 256M max_heap_table_size = 256M thread_cache_size = 16k table_open_cache = 2000 table_definition_cache = 4K open_files_limit = 3K key_buffer = 2048M innodb_buffer_pool_size = 640M long_query_time = 5 join_buffer_size = 2M max_connections = 250 wait_timeout = 28000 interactive_timeout = 28000I was struggling with MYSQL crashes, and nothing stuck out in the error logs that clued me in. The changes I made (so far) have stopped the crashes, however, I am still seeing the high load.
I don’t have many plugins, and most are the ones that are VERY popular, so nothing off brand. Here are my server specs:
Intel Core 2 Core2Duo E8400 3.0 GHz
8 GB DDR2-800 SDRAM
1 Gbps Uplink Port Speed
CentOS 6.0 – 64 BitHere is my phpinfo: https://www.theblackvault.com/phpinfo.php
Here is a screen shot of my ps -awfux.
ANY help would be greatly appreciated.
