hey all,

on the night of 31-12 to 1-1 i had an insane log drop on my ELK-stack cluster.

the cluster exists of 2 elasticsearch clusters 8GB memory each and 1 logstash server 4gb memory.  
they are recieving syslog messages from about 350 servers.

does anyone have an idea what might be the cause of this?

after a restart of the logstash server things were working for a while,  
but after a couple of days it started dropping logs again.
