Here is the lowdown.
Our news server :
64MB RAM
Pentium 100 BSDI BSD/OS 2.0.1
Running INND unoff 4 with the sharedactive patch (same problem without
the patch)
Machine is dedicated to news server only (no other big apps).
Here is the problem ... After a reboot, the machine runs fine for a
period of about 24 hours (sometimes less). Then, it stops allowing
newsreader connections. The log files show the message (when this
problem is occurring) of:
flagstaff innd: ME can't fork /usr/contrib/lib/news/in.nnrpd Cannot
allocate memory
I have tried numerous things. I made sure that the user news was not
running out of data space by using limit (cputime, datasize, filesize,
openfiles, maxproc, memoryuse, stacksize) unlimited. I also recompiled
INN with the sharedactive patch. For some reason, it is still doing the
exact same thing. I am including some output from vmstat 5 below. The
only thing that looks strange to me, is that there the fre collumn starts
at about mid 40's and then slowly drops (is this normal??) until it hits
around 7600. At this point, the problems are occurring. Also, the page
faults seem to jump very high at points. I am not sure if it is normal
for them to jump this high or not. Basically, I need to know if anyone
else has experienced the same problem, and if so, how was it resolved.
Any and all advise or suggestions in this matter would be greatly
appreciated.
Thanks,
Greg
