dumpcap memory usage during 802.11 capture

[David Seares <dave () seares net>]

Hi,

Probably a stupid question about dumpcaps memory usage.

I am trying to capture packets over a long period of time, splitting
captures over multiple files each 5 minutes.

I noticed that after just 12 hours of capturing the memory usage (vmem) of
dumpcap had reached 8GB.

Is this expected?

Assuming that this value is going up this would surely crash my computer in
the end.

One thing to note is that I am capturing IEEE802.11 traffic using the
unencryption feature of the packet dissector, could this cause this sort of
memory usage?
