APC Uptime is very low
Here is my server information :
- APC Version : 3.1.9
- PHP Version : 5.2.17
- Server : LiteSpeed 2 CPU license
- PHP : DSO.
- cPanel : Yes.
- WHM : Yes.
I rarely open my apc.php, i usually open it on my peak traffic, about 3-6 times a day. Most of the time i open it, uptime is low, ranged from 20 minutes to 5 hours. However i've never received any error e-mail such as when my Litespeed restarts by itself.
APC memory usage is low, 10-25%.
Fragmentation is low too, < 1%.
I feel that once im on peak time, apc restarts itself because uptime back to 1-3 mins.
Code:
root@mybox[~]# free -m
total used free shared buffers cached
Mem: 12001 7445 4555 0 1289 3808
-/+ buffers/cache: 2347 9653
Swap: 2047 0 2047
Here is my APC setting
Code:
apc.cache_by_default 1
apc.canonicalize 1
apc.coredump_unmap 0
apc.enable_cli 1
apc.enabled 1
apc.file_md5 0
apc.file_update_protection 2

apc.ttl 0
apc.use_request_time 1
apc.user_entries_hint 4096

Is there anything i can do to make uptime longer? |
