Apologies to the group - I didn't realize my posts were being moderated
until I had attempted post the same comment several times.
I enabled the message_cache_off_heap setting and it seems to have resolved
slow GC crash issue.
message_cache_off_heap = true
message_cache_spool_dir = /var/lib/graylog2-server/message-cache-spool
With this setting on, my 20G heap stays between 5G and 10G utilized.
However, as far as I can tell the message_cache_spool_dir seems to grow
until the disk fills up.
Has anyone experienced this? Is there a cleanup operation I should be
performing?
