Apologies for jumping someone else's Issue, However I am also having same issue

my elk container worked fine for a month and then suddenly stopped working

below are the details

[root@server1 ]# ulimit -n 65535

[root@server1 ]# sysctl vm.max_map_count vm.max_map_count = 262144

[root@server1 ]# cat /etc/sysconfig/docker OPTIONS="--default-ulimit nofile=1024:65536"

@jaydeepjc unless the logs (where your message is clipped) show anything interesting, I'd still suggest that this is a memory issue (memory as in RAM available for the container). If your container's been running for a while and/or if memory hasn't been specifically dedicated to the container, then the container could become short on memory causing Elasticsearch to fail on start-up.

[jaydeepch15]

What can be done, I tried resting container as well as host machine, it didn't helped. Any suggestions?

[spujadas]

Assign more memory to your container, not much else that can be done I'm afraid.

Got it, Thanks :)
