New memory leak in ~1.3.67 ?

Since upgrading from 1.3.57 to 1.3.67 (and 1.3.71) our ISP server machine
has begun leaking memory. I haven't been able to gather any exact data,
since our machine has died only 3 times (yet), and the last one happened
while I was watching. Before that we had absolutely no idea has had
happened, since Linux has nasty habit of not unblanbking after crash.

Anyway, here's everything that seems important:
- No IDE
- 2x SCSI disc, 1x SCSI CD, connected to AHA-2940 ultra. Doesn't seem to
be disk buffer problem.
- 3c509-C ethernet adapter.
- Every time there was at least one active PPP connection and I think
either PPP or generic networking code is leaking.
- Oops, almost forgot that we added another "dumb" 16550 serial card to
the machine. However I doubt that serial code would mess up like that?

So far my insta-fix for the situation was to add another 32MB of RAM to
the machine and start observing memory situation nearly hourly. So far
with uptime of 26 hours 20 Mb of RAM is marked "in use" without anything
using it. (about total of 30 Mb is in use on "idle" machine. Normal
figure should be ~10M...)

So here goes the oh-so-often-uuttered-phrase:
"Has anyone else observed similar problems and if so, what do you have in
common?"
