I was having this problem for a long time with ctx-16 a crash every 24
hours, I downgraded to ctx-15 and have now have 7days uptime so far *knock
on wood* I know many people are having problems with ctx-16 may be you
should drop down. *shrug just a suggestion*

Subject: [vserver] 2.4.20-ctx16 kernel crash

Ok. Here we go. Crashed again. Got me another 48 hours of run time.
Just curious is ctx-14 or ctx-13 more stable then 16 and 15 ?
If I understand it right earlier version then 15 do not have
functional udp stack ? So doing snmp calls from inside one vserver
will not work at all if I go with anything prior to 15 ?
How does this work for named ? It's using UDP ? Are you not able
to run named in a vserver in < ctx-15 ?

Ok here is my ksymoops from the crash I had this morning. I had to
type this thing down manually since I hadn't had a chance to fix up
the serial console yet. But from looking at a previous posted ctx16
crash info it's the same ud2a that triggers the crash.
I'm NOT a kernel programer. Been ages since I did any C/C++ programing
at all. I not done anything but php/perl/mysql/html coding for the
last 2 or so years.
