    Suddenly, I got alot of these error in /var/log/messages
    Code:
    Jan 10 15:47:08 myserver kernel: lsphp4[3480] general protection rip:55f47e rsp:7fffc370ce60 error:0
    Jan 10 15:48:03 myserver kernel: lsphp4[3592] general protection rip:55f47e rsp:7ffff37ebf40 error:0
    Jan 10 15:48:20 myserver kernel: lsphp4[3580]: segfault at 0000000000000011 rip 000000000055f47e rsp 00007fff62bb9310 error 4
    Jan 10 15:49:03 myserver kernel: lsphp4[3670] general protection rip:55f47e rsp:7fffd4f496a0 error:0
    Also this message with logwatch:
    Code:
    --------------------- Kernel Begin ------------------------
    WARNING:  General Protection Faults in these executables
        lsphp4 :  203 Time(s)
    ---------------------- Kernel End ------------------------- 
    The server crashed very frequent and there are many lsphp4 process filled up very fast. I have to setup a manualy cronjob to kill those process every minute or else the server load will goes above 100, and the waitQ is high then server became dead.
    I checked and there is no sign of DDOS or DOS.

    What is the problem?

    I am running CentOS 64 bit, 2x Quad-Core AMD Opteron 2344 HE, 16GB of RAM

    have you changed anything related PHP? php.ini? opcode cache? It is a PHP problem, not LSWS itself.

    strace lsphp4 process see if you can catch one crash.

    No, I did not changed anything. Just suddenly LSWS is crash too frequently, and i dont really know why.

    Is this a custom php installation? If so, I would try to recompile php with lsapi support. You could have a bad php installation.
