queue max run limit using "at" command

[ikbea]

Hi all,

When users use "at" command yesterday, the at job cannot run and the following error showed in /var/adm/cron/log:

! a queue max run limit reached
! rescheduling at job

Refer to a thread "queue max run limit reached in /var/adm/cron/log", it mentioned the following:

----------------------------------------------
:
Look at your /var/adm/cron/queuedefs file. It's the configuration file that specifies how many cronjobs can be handled by cron simultaneously. It's usually in this format.

c.xjyn

This meanx 'x' number of cronjobs can run simultaneously.
:
----------------------------------------------
Is this same for "at"? In server, the queuedefs content:
a.4j1n
b.2j2n90w

Is this mean 4 "at job" can run simultaneously ?

Any side-effect if I increase the value ?

Check also the cumulative cron patch on your system.

Hope this information can help you.

man queuedefs

You at job queue is 4 simulataneoud jobs.
You will have to increase it and restart cron daemon.
