Need some advice on how to resolve this issue. I setup an ELK box (1 box) that is working great, except every 4 days or so logstash runs out of JVM heap and then doesn't do much processing and I have to do a restart to fix it again.
See below screenshot of the JVM steadily increasing:
Any advice what I can do to resolve this problem, the ELK instance is setup with 4GB of RAM. I don't think it is a RAM capacity issue as it is fine initially and overtime fills up the heap.
