    www_server stops unexpectedly

    • Article Type: General
    • Product: Aleph
    • Product Version: 18.01

    Description:
    Earlier this week, on December 11, at 12:20 our www_server just stopped. I've looked through the log, www_server_4998.log.1112.1231, but I don't see anything that gives me a clue.
    We are a Solaris site, on SP 1323.

    Resolution:
    When a www_server is brought down by an aleph process, such as util w/2 or aleph_shutdown, its log has lines like the following:

    Server received stop command
    Server killing child pid: 21851
    Server killing child pid: 21900
    ...

    The end of the www_server_4998.log.1112.1231 has no such lines. This means that one of three things happened:

    1. the www_server processes were terminated by a "kill" command
    2. the www_server processes died of their own accord, without any indication of in the log of a problem
    3. the www_server processes continued existing but stopped responding

    (I have never seen #2, but I suppose that it could happen.)

    If/when this happens again, you should do "ps -ef | grep www_server" to distinguish case #3 from cases # 1 and 2.
