    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.filters 
    apc.gc_ttl  3600
    apc.include_once_override   0
    apc.lazy_classes    0
    apc.lazy_functions  0
    apc.max_file_size   20M
    apc.mmap_file_mask  
    apc.num_files_hint  1000
    apc.preload_path    
    apc.report_autofilter   0
    apc.rfc1867 0
    apc.rfc1867_freq    0
    apc.rfc1867_name    APC_UPLOAD_PROGRESS
    apc.rfc1867_prefix  upload_
    apc.rfc1867_ttl 3600
    apc.serializer  default
    apc.shm_segments    1
    apc.shm_size    512M
    apc.slam_defense    1
    apc.stat    0
    apc.stat_ctime  0
    apc.ttl 0
    apc.use_request_time    1
    apc.user_entries_hint   4096
    apc.user_ttl    7200
    apc.write_lock  1
    Is there anything i can do to make uptime longer?
