Hi guys !
I have a GL cluster consisting of 3 virtual CentOS Servers, each one with 8 Cores and 12 GB of RAM.
In each server I have installed GL 2.3.0 and ES 5.5.1.
I recently performed the upgrade from GL 2.2 and ES 2.x. After I performed the Upgrade, GL Java processes started using a lot of CPU, averaging 300 - 400% per process.
I’ve trying to take some thread dumps, but it looks like JVM is not respondind.
I enabled JMX, and using VisualVM i have managed to perform a CPU profiling. Attached, you can find some screens of the CPU sampler, you can see there are some KafkaJournal related methods taking a lot of CPU time… please help me with this… I thing it could be a bug…
