That is one. Another one is to run "top" in batch mode and
send stdout to a file. From there you might monitor swap
space and see if used swap increases. If it does, see what
process grows.

If you have a constantly growing smbd, send it the

smbcontrol <smbd-pid> pool-usage

message and send us the output.
