Re: [keycloak-user] Uncaught server error: java.lang.OutOfMemoryError: Java heap space
Hi Arun,
Yes, we have seen this issue before. A temporary remedy has been to increase jVM's
maximum heap size, among other things, like changing the eviction rate and infinispan
cache sizes.

space
Hello,
We ran keycloak with some basic load (like auth, gettoken) for few hours at theand after
sometime Keycloak threw an Out-of-memory error. Has anyone faced similar kind of problem.
Would be keen to know what was done to mitigate.
Version of Keycloak -> 4.0.0.Final.
