Ok, so, I'm not even sure how to search on this one.
Right around midnight 1/28-1/29, my fleet server agent had it's debug logging turned on. That server went from 50 docs/min to 60,000 docs/min.
Didn't figure it out until this morning when my snapshot storage pushed my nfs volume into 90+% usage.
I'm running 8.6.1 on my cluster and that fleet agent.
Any ideas?
