Jenkins isn't accessible due to several errors

[Mehdi Hayani]

Hi Team, 

For the last two days, each time I came, I found that jenkins was down (Error 503) Tomcat status was "running" but the application couldn't be accessible , I had to restart the service in order to make it work

The problem is that when checking the log files, I found many errors that doesn't allow me to know  what really made Jenkins inaccessible:

I'm really afraid that this problem appears again, that's why I would be very grateful If you can help me solving it :) 

Thanks in advance.

PS: I'm using Jenkins 1.480.2 running under Tomcat 7

Mehdi

You have multiple Out Of Memory errors in there; you need to investigate why your Jenkins process is out of memory. It could be that the system itself is low on available RAM, or that you need to configure your JVM to have a larger heap available.

Okk thanks, I'll check.

meanwhile, you have any idea why I Get this warning ?? 

[Christoph Kutzinski]

Which JVMs are you using for Master and Slave? The error is a serialisation incompatibility between these two.
