    I am using lsws 4.2.5 with LSAPI 6.4, PHP 5.3.27
    And APC is restarted often again (uptime 0-1 mins, max 5 mins).

    I have tried to :
    - switch to lsws 4.2.4
    - switch to lsws 4.2.5 again
    - increasing Memory Soft Limit (bytes) & Memory Hard Limit (bytes)
    - reducing shm_size

    I still have lot of memory
    Code:
    xxx@xxx[~]# free -m
                 total       used       free     shared    buffers     cached
    Mem:         24097      16047       8050          0       1986       9732
    -/+ buffers/cache:       4327      19769
    Swap:         2047          0       2047
    
    Some lsws setting :
    Run On Start Up >> Run On Start Up
    Max Idle Time >> -1
    External Application Abort >> No Abort

    (more lsws setting in attachment)

    My apc setting

    ok after i am offline for some hours (still 4.2.5), i just checked apc uptime and it was 1 hour and 45 minutes. but when i opened heavy page (admin page), and lot of processes there, the uptime suddenly dropped again & uptime is short.
    -----
    Update : i am trying 4.2.4 now, and will see the uptime in 1 hour.
    Meanwhile i see this warn log (on attachment), is it somehow related with APC uptime?
    ------
    Update 2 : after trying 4.2.4 for 15 minutes, even when i opened heavy page, APC seems more stable and uptime can reach at least 10 mins easily now. Will watch more.
    -----
    Update 3 : I've confirmed that 4.2.4 works better than 4.2.5 in term of APC uptime.
    Maybe you can do some testing to confirm this?

    Your apc file mask seems wrong if I remember correctly it shoud be 6 uppercase Xs in the config file (XXXXXX). maybe this is the result you have shown us and not the actual config file ?

    Yes true, it is from apc.php result.
