1. Describe your incident:
There are Graylog nodes on which the garbage collector runs too long. Garbage collection runs should be as short as possible. Please check whether those nodes are healthy. (Node: 255ad1c2-6480-40be-9199-f26939f66989 , GC duration: 4825 ms , GC threshold: 1000 ms )

2. Describe your environment:

3. What steps have you already taken to try and solve the problem?
increase the JVM arguments: -Xms1g -Xmx1g to JVM arguments: -Xms4g -Xmx4g
in /etc/default/graylog-server and /etc/sysconfig/graylog-server
and still the same after restart graylog server and service check by running the command grep “Running with JVM arguments” /var/log/graylog-server/server.log
