I once had issues with malformed cron entry constantly spawing new process which never end (wrong syntax for instance iostat or alike,bad scripts ), reaching queuedefs limit (maximum concurent cron/at jobs limitation).
So roots cron was malformed hitting the limit, and all other users cron's didn't work.
If this works the other way (i don't see why not), a user could compromise cron of the entire system with a simple entry
I had one recently where the disc cabinet containing some of the scripts mentioned in root crontab failed. The cron daemon soon reached the queue limit as it queued more and more impossible jobs with hung I/O.
Well worth speed reading the cron log.
As a minimum:
Code:
grep "max run limit" /usr/adm/cron/log
I assume that /home/report is on a normal mounted partition (not NFS or whatever).
To all that contributed to this issue, many thansk for the support. Problem now solved, with a reboot. But it would help to know why this was happening
crontab again not working,

After running:
Code:
grep "max run limit" /var/adm/cron/log | more
I got the following result:
Code:
! c queue max run limit reached Fri Apr 13 14:50:00 SAST 2012
! c queue max run limit reached Fri Apr 13 14:50:00 SAST 2012
! c queue max run limit reached Fri Apr 13 14:50:00 SAST 2012
! c queue max run limit reached Fri Apr 13 14:50:00 SAST 2012
! c queue max run limit reached Fri Apr 13 14:51:00 SAST 2012
! c queue max run limit reached Fri Apr 13 14:51:00 SAST 2012
Is that something wrong?
But if I run
Code:
more /var/adm/cron/queuedefs
I have the following:
Code:
a.4j1n
b.2j2n90w
So no
Code:
c
is present
Please can you help

Hi
I think now the problem is solved, what I did was to change the text "a.4j1n" to "a.10j1n" in file "/var/adm/cron/queuedefs", them stopt/start cron deamon. So
nothing appears now, when I run "grep "max run limit" /var/adm/cron/log | more" and entries in the crontab are being executed.
