Ah, I think you have been looking at the wrong numbers.
You are only using 228259M, (~222G, not 355G)
111823M is unallocated and currently used for buffer/disk cache.
This amount will always grow until it ends up using almost all the 'free' memory on the machine.
The reason why the OOM killer isn't killing anything is because you still have over 128G of ram free.
I added up all the ram usage from the output of bro top, and adding some overhead for the rounded amounts measured in gigs, came to
Minus splunk, that does still leave about 150G unaccounted for.
I believe some of that will be used by packet buffers in the kernel, depending on how you have configured pf_ring.
But even at a huge 1G buffer for each of 20 workers (which I think is much much more than it uses by default) that is only another 20G.
