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.
The described scenario sounds familiar. I've seen it happening for
quite some time. I just thought it had something to do with
/hurd/term and pseudo terminals. But no hard evidence for that. Are
you guys sure it is pflocal?
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.
Yes please!
Maybe it is related to the pflocal changes without the corresponding new
glibc, and updating glibc fixes that.
Probably not. It has been happening to me since before tinkering with
pflocal.
