I don't know whether it fires at all.
On my gateway, for some weeks, I periodically run out of MBuf Clusters every 
some days (now I know, I monitor mclpl and keep re-booting before actually 
hitting the limit). Looking for possible leaks, I noticed that IPFilter uses 
MBuf Clusters to send RST packets. So I dug through the code looking for 
possible leaks.

Yes, of course. I didn't figure out whether some malicious packet (which is 
somewhat likely on a gateway) could be arranged to tigger that case.

So, as you aggree it's a leak, I'll insert a
	FREE_MB_T(m);
and install the resulting kernel (I'll have to re-boot anyway sometime soon) 
and see if the problem disappears.
