Thanks for your response.
I do see the following OOM message in my system logs on the logger process ID:
Sep 23 18:48:00 kernel: Out of memory: Kill process 10439 (bro) score 787 or sacrifice child
Sep 23 18:48:00 kernel: Killed process 10439 (bro), UID 0, total-vm:301983900kB, anon-rss:195261772kB, file-rss:2592kB, shmem-rss:0kB
Wonder why its taking so much memory, I have 251G and 99G swap on this server.
total used free shared buff/cache available
Mem: 251G 66G 185G 4.2M 488M 184G
Swap: 99G 1.1G 98G
Below is the output of "broctl diag logger", ran after the logger crashed.
[logger]
No core file found.
Bro 2.6.3

The logger is threaded, so seeing CPU > 100% is not necessarily a problem.
Have you tried running "broctl diag logger" to see why the logger is crashing? Do you have any messages in your system logs about processing being killed for out of memory (OOM)?
