Max Queue Limit Reached

Max Queue Limit Reached

Post by Thana Letchu » Tue, 02 Dec 1997 04:00:00



Hi,
   I have a sco open server ver 3 running on compaq. I often encounter the
following error on the console :-
    b queue max run limit reached <date>,
    rescheduling at job <date>.

How do I prevent this error from occuring and what is the reason for its
occurance?. Does this degrade the system's performance?.
Thanks for your help.

Regards,
Thana

There's a nice article on this in the SCO Technical Articles database,
http://www5.sco.com/.  "b queue" is the batch queue used by batch(C).
It is limited precisely to prevent batch jobs from dragging down
interactive performance.  You can change the limits.  If you don't, your
batch jobs execute normally, but at a later time than originally
scheduled.  That might or might not be a problem, depending on the
purpose of the batch jobs, and how long they are delayed.

1. inode overflow; c queue max run limit reached

I've had 2 occurences of the following:

First I receive:

Audit: Collection file inode table overflow
Audit Subsystem termination due to irrecoverable error.

Then about 1 half hour later, something bad happens to cron.  I have a
short job running each minute (does netstat -m to a file); this stops
running; I come in at about 0900 and find the following messages
repeating 6 times each minute:

c queue max run limit reached Wed Nov 13 09:17:00
rescheduling a cron job Wed Nov 13 09:17:00

The date and time are updated to system time.

Using cron tab to stop my 1/minute netstat does not stopp thes messages.

Using ps, I find many job whcih are "/etc/cron" starting about the time
that the last succesful cron job ran, space 1 minute apart for an hour or
two;  similarrly I find a large number of jobs that look like:

root 2794 2793 0 01:57:00 ? 0:00 dlvr_audit 847880520 19 26 2793 cron 6
root 0 run an at/cron session all securi

where the preceding 2 lines are really on long line (and yes, it really
does break off in the middle of the word security).

Any help much appreciated.

This is SCO OSE 3, UNIX 3.2v4.2 via Compaq smartstart.  I've gout two
