Apache side without corresponding errors on the JRun side (Apache was
fielding and forwarding requests to JRun, but JRun wasn't running and wasn't
logging problems). The only way to determine what happened relative to JRun
is to look at the log files for each JRun server - not just the event log
but also the err and out files too. If they don't contain any information,
then it will be difficult to tell. Does JRun run on the same machine as
Apache, or are they distributed? Are there any system-level log files
available (like Event Viewer on Windows) that might provide additional
information about what happened? Thanks.

Subject: JRun mysteriously crashing, strange errors in Apache
Over the holiday, our distance learning campus webserver crashed, and
our alarm system failed to notify anyone in the office (meaning that no
one discovered this until yesterday morning). My boss managed to get
the site up and running again, but when I came in and checked the error
logs for JRun, I can't find anything out of the ordinary, in either
default_event.log or admin_event.log (I found a broken pipe error in
default_event.log but that is dated from this morning and is thus
unrelated to Thursday's crash). On the other hand, my error_log from
Apache shows the following line many many many times starting on Thursday:
[notice] jrApache[7535] JRun is busy. [15] dropped while sending command.
This message also shows up frequently, beginning at 9:05 on Thursday,
November 27:
[notice] jrApache[7535] Couldn't initialize from remote server, JRun
server(s) probably down.
...however, I cannot find anything in either default-event.log or
admin-event.log (or earlier versions of those files) that corresponds to
that time.
The Apache logs indicate that the computer was running the entire time,
as was Apache itself.
Does anyone have any idea as to what might have happened, or where else
I might be able to find more information?
