I am on a dedicated server - running multiple portals in respective virtual directories. Some of the previously loaded websites are using Zend opcode cache. While my new commerce portal uses an APC based cache and I have migrated this website to the new server.
I am having frequent internal server 500 errors and crashes.
I am having following config:
- PHP 5.4.27 and APC 3.1.13,
- Centos server with about 4 GB ram,
- APC is using php-fpm
Zend opcode cache config:
Opcode Caching Up and Running
Optimization Enabled
Startup OK
Shared memory model mmap
Cache hits 71322
Cache misses 1049
Used memory 13544916
Free memory 42838688
Wasted memory 10725260
Cached scripts 298
Cached keys 309
Max keys 3907
APC config: shm_size = 2024M ..and so on...
Could this be a possible reason for crashes? Do i need to disable one of them or can they run together. I am afraid disabling zend should not cause issues to other websties - so just wanted to be sure?
