5.3.6 CAS 100% CPU

[thomas]

Hi all,

I recently migrate my cas system from v4 to v5.3.6.

Everything works fine for logging, but I have a problem with CPU load on server.

After some time (can be minutes or hours), CPU load raises and reach ~100% (1/2% before), no matter how many cores I allocate to the VM (if I set 4 cpu, the 4 are ~100% cpu).

I'm not a java expert, and I don't know how to find the origin of this problem.

I have few TGT delivred (~80), java memory is OK (45%).

I use apache-tomcat-8.5.37 , and a recent java version (jre1.8.0_211).

Any advice should be appreciated, if you need more informations jusk ask.

regards

thomas

Hi,

I would recommend doing a threads dump to see what's going on inside the CAS server.

Thanks.

Best regards,

Jérôme
