I have a VPS running on centos 5 with 2 GB ram. I run a IP.Board forum on that server. Recently my server was hacked and I had to format the disk and start again. I was using APC cache before and it was running fine. But now when I enable it the forum goes offline. I am at my wits end. Please help me to get it working. Lemme know if I need to provide more info about my server. Regards
I am using the following configuration I found on a StackOverflow question: https://stackoverflow.com/questions/3570131/optimize-apc-caching
apc.enabled=1
apc.shm_segments=1
; I would try 32M per WP install, go from there
apc.shm_size=128M
; Relative to approx cached PHP files,
apc.num_files_hint=512
; Relative to approx WP size W/ APC Object Cache Backend,
apc.user_entries_hint=4096
apc.ttl=7200
apc.use_request_time=1
apc.user_ttl=7200
apc.gc_ttl=3600
apc.cache_by_default=1
apc.filters
apc.mmap_file_mask=/tmp/apc.XXXXXX
apc.file_update_protection=2
apc.enable_cli=0
apc.max_file_size=2M
;This should be used when you are finished with PHP file changes.
;As you must clear the APC cache to recompile already cached files.
;If you are still developing, set this to 1.
apc.stat=0
apc.stat_ctime=0
apc.canonicalize=1
apc.write_lock=1

apc.include_once_override=0
apc.lazy_classes=0
apc.lazy_functions=0

I used the same tutorial to install apc as before. It can be found at this link
