    Litespeed 3.1.1 enterprise
    Ruby-LSAPI 2.5

    I have 5 servers running litespeed and a Rails application. Noticed occasional messages coming up in dmesg and /var/log/messages on a couple of them like this:
    lshttpd[13545]: segfault at 00005d947ee9859c rip 0000003c3ac6fd00 rsp 00007fffffb7bb18 error 4

    lshttpd[13542] general protection rip:3c3ac6fd00 rsp:7fffffb7bb18 error:0

    Another server will have similar messages:
    lshttpd[1045]: segfault at 00000000ffffffff rip 000000330966fd00 rsp 00007ffffff52588 error 4
    lshttpd[1161]: segfault at 00000000ffffffff rip 000000330966fd00 rsp 00007ffffff52588 error 4
    lshttpd[1195] general protection rip:330966fd00 rsp:7ffffff52588 error:0
    lshttpd[1137] general protection rip:330966fd00 rsp:7ffffff52588 error:0

    The application seems to be working ok - I suspect a RAM issue on those servers, would you agree?

    It might be a bug in lshttpd. Do you got core dumps? What kind of OS it is? Linux or something else?

    We're using Fedora Linux, Yes in /tmp/lshttpd there is a directory called bak_core with a few core files. The error seems to be coming up at 5 minute intervals - I haven't associated any cron or application process to that timing.

    Please update to the latest release, install GDB, set administrator's email from the web console. A crash report will be sent to you with some debug information. Please forward that email to bug @ .... .
