Jenkins dump analysing

[Dmitrijs Shahlovs]

Hi all,

I am running Jenkins 2.7.4 on windows machine(as windows service).

For now we are enforced to restart Jenkins every couple days, because performance degrades,

From memory dump I can see, that 60% of size is taken by char[] class.

There are 65000 almost identical instances:

[number from 10 to 65000]

GC root: cb->out->config-><classLoader>->klazz->value->[%number%]->[%number2%]->table->number[%number3%]->segments->map->globalClassValue-><class> (Java frame)

Can I somehow track - what is causing this? Or maybe this is expected behavior?

Regards,
Dmitirjs
