Problems with innd on AIX 3.2.2

Post by Bob Sloa » Sun, 11 Apr 1993 01:41:57



Hi All,

I am just getting started running INN 1.4 on our RS/6000 350 running
AIX 3.2.2.  Everything is working OK, except innd keeps disappearing.
This has happened 4-5 times in the past week.  The message in errlog
is:

INND exiting because of signal

and in news.notice:

Apr  8 16:58:14 stat1 innd: ME shutdown received signal

The system errlog is getting messages like:

C5C09FFA 0408165993 P S  SYSVMM SOFTWARE PROGRAM ABNORMALLY TERMINATED

indicating that we are running out of virtual memory, so apparently
the system is killing innd to get paging space back.  We have 96mb
real memory and three 96mb paging spaces on three separate disks. Is
there anything that can be done to make innd stay around, or do I just
need to add a bunch more paging space?

It's that strange memory allocation policy of AIX again.  The proper
behaviour would be for innd to eat all your swap and wedge out
everything else ;-)

The best solution might be to run innd with a limit on memory.  Try
starting it with `/bin/sh -c "limit datasize 96m; exec innd"' or hack
main() to call setrlimit(2) early.  Malloc will return a NULL if innd
tries to exceed the limit.  I assume innd will know what to do (ask r$).

Report this to IBM and they will tell you that it is a "feature".
They WANT the os to start randomly[*] killing processes when
swap space is getting low.

Tom
[*] Ok, it's not random.  The OS selects the most recently
started process and kills it.  Sort of wants you to take their
latest adverts, highly them every time they use the word "reliable"
and mail it to their CEO's desk.  Include a box of cookies
so he understands what you're saying.

Use schedture to disable this or limit the m parameter to something real

Well, this problem is sucking slowly (several weeks !)
The PTFs is already applied with some distributions of 3.2.3e.

Does anyone have a config.data file for aix that they would be willing to
share? I'm working on installing inn 1.4 on a aix 3.2.3 system right now.
thanks,
/P

There's a great example in the install manual that works fine ...
