This happens when old classes are not cleanly unloaded, most likely because jetty didn't stop correctly.

WORKAROUND: stop rudder-jetty ; check that jetty is stopped ; start rudder-jetty

History

#1 Updated by Félix DALLIDET 15 days ago

It happend when installing the auth-backend plugin which was already installed on the server.
The install did not seem to trigger any webapp restart.

  • Tags set to Sponsored
  • Target version changed from 5.0.7 to 4.3.10
  • Severity set to Major - prevents use of part of Rudder | no simple workaround
  • User visibility set to Operational - other Techniques | Rudder settings | Plugins
  • Priority changed from 0 to 84

We also saw it during a normal reboot, so I'm setting the priority to a higher level. We need to at least find a way to stop the webapp, a NoClassDefFound is always a big problem.

The problem with that exception is that it happens on a separed thread pool.

The general idea would be to have something looking at the log file and doing other things when that happen.
Something =
- rudder (but if rudder is broken, not good)
- jetty (but that means special handled code in jetty)
- something out of rudder/jetty (script in cron)
