npppd hangs (under load)?

Marko Cupać
Hi,

I wrote already on @misc, but as I had kernel panic I am reporting it
here as well.

Recently my npppd server got an increase from ~20 to ~200 concurrent
PPTP users. It worked fine with same configuration on various hardware
for 7 years (right now on HPE ProLiant 360 gen9).

Last few days it is very unstable, meaning it works fine for a few
hours, taking just a fraction of a percent of CPU, but then it quits
taking new connections and takes 100% of single CPU core.

Photo of panic here (sorry have no serial console set up):

Hi,

thanks for info. Any chance this gets released as binary (sys)patch for

Also, I just had another npppd hang, even with pipex disabled (in
npppd.conf, it's still in sysctl.conf). Any tips how to troubleshoot it?
