RussianQuestion
On the gentoo Linux server I use, I've just upgraded APC from 3.0.19 to 3.1.4 and it appears as if something is not working properly there. It appears as if cache entries which should have been deleted (either explicitly or via TTL expiry) stay in place and so cache use keeps growing until it reaches the max usage memory and then the server becomes extremely slow.
Anyone with some experience on this upgrade?
Thanks
Here's my apc.ini
extension=apc.so
apc.enabled="1"
apc.shm_segments="1"
apc.shm_size="1536"
apc.num_files_hint="2500"
apc.ttl="7200"
apc.user_ttl="86400"
apc.gc_ttl="3600"
apc.cache_by_default="1"
;apc.filters=""
;apc.mmap_file_mask="/tmp/apcphp5.XXXXXX"
apc.slam_defense="0"
apc.file_update_protection="2"
apc.enable_cli="1"
apc.max_file_size="5M"
apc.stat="0"
apc.write_lock="1"
apc.report_autofilter="0"
apc.include_once_override="0"
apc.rfc1867="0"

Solution
This was seemingly a Gentoo linux related bug. I've reported it on http://bugs.gentoo.org/show_bug.cgi?id=343485 and it's been fixed for APC 3.1.5
OTHER TIPS
I had problem with APC 3.1.5 when I set the apc.shm_size with only the numeric value.
Try out apc.shm_size="1536M", maybe it helps (the default value in the documentation also uses this formula)
