I've never seen such a problem either, and I recently piped 8 tb through pflocal without seeing any sign of any kind of leak.  I'd say it is not reproducible anymore.

Has anyone been able to reproduce this since 2000?

I, as Samuel, haven't had such problems.

Note: I personally never had such troubles.  Someone should try to stress pflocal and see how well it still leaks.

I am seeing this, too, but it's news to me. Today is the first time I really
saw it happen.

pflocal get's suddenly nervous, and memory usage blows up, within a few
seconds it sucks up all availalable RAM, and then swap (but slower). I saw a
swap decrease of 4 MB every few seconds.

It's hard to get diagnostic info at this stage. I could run one "ps aux",
which showed a memory usage of 66 MB, but after that, I could not get the
number of ports nor the number of threads. I will try to get more info.

Maybe it is related to the pflocal changes without the corresponding new
glibc, and updating glibc fixes that.

Anyway, for the record, I submit it as a Debian bug. Please drop
