Our Jenkins instance keeps crashing

[David Aldrich]

Hi

 

Jenkins is crashing on me several times a day.  I am running Jenkins 1.552 on Centos 5, in a VM. Jenkins used to be stable for us. The only symptom I see is that my browser shows:

 

“An internal server error occurred. Please try again later.”

 

I don’t know where to start debugging this.

 

The Jenkins system log has several severe errors/warnings:

Any suggestions what I should do please?

 

Best regards

Fixed exceptions in System Log by deleting rogue .jpi file and enabling JavaDoc plugin.

 

Will wait and see if that fixes the crashes.
