Hello,
I have an app deployed using JavaMonitor. I run just a single
instance. I have it scheduled to restart daily at 0300.
At random times, I'll have users contact me that "can't log in".
Indeed, the main URL shows "No instances available", and JavaMonitor
shows the instance to have Refuse New Sessions ON. Flipping that
OFF using the red button in the All Instances row solves the problem.
I _assume_ the app goes into Refuse New Sessions mode prior to a
restart, yet it's showing the next restart to be "Wed @ 03:00",
which is some six hours away. The log shows nothing unusual prior
to lines like this:
Mar 09 21:05:06 PBF[2001] DEBUG NSLog - !!! Request will be
REDIRECTED to non-refusing instance </Apps/WebObjects/PBF.woa>
I assume that's just a symptom. So what can cause JavaMonitor to
spontaneously drop an instance into refusing new sessions?
We also had this problem, caused by an app that was restarting in the
same timeframe as Nagios was checking a DirectAction, we moved the
restart schedule outside our monitoring timeframe (4am to 11pm) and
problem was fixed. Check your Apache logs to see if you have any
requests around 3am for your app. _______________________________________________
