Hi All,
Couple of months ago I upgraded the Zeek cluster from 2.5 to 2.6.1
(compiled with the jemalloc support).
I have started seeing increased memory usage by the workers.
I have two physical sensors, each running 18 Zeek worker processes LB by
PF_RING.
Not loaded any custom scripts, just the basic scripts that are enabled by
default in local.bro (also have misc/scan disabled).
I just did a top on one of the boxes and here's the output (specially two
Zeek processes -*13632, **13611* using >10% memory which is ~11G)
Also, attaching a weekly available free memory graph for the system.
