Not able to telnet to server

[Eddie Salvatierra]

We have a server HP 9000/813 running HPUX 11.00.

User would log in using telnet and it just hung on "Please wait...checking for disk quotas"

I was able to log on via the console and found multiple cron processes. We were not able to kill the processes but was able to stop cron.

We ended up rebooting the server to fix the problem. In my post investigation I found multiple entries of this message in the cron log ;

! c queue max run limit reached Mon Mar 8 04:32:00 NZDT 2004
! rescheduling a cron job Mon Mar 8 04:32:00 NZDT 2004

I searched ITRC and found that there was a known bug with cron. However, I have the current patch to fix the bug.

Cron Level info and patch installed below;

[/root] >> what /usr/sbin/cron
/usr/sbin/cron:
$Revision: 82.9.1.29 $
PATCH_11_00: hpux_rel.o cron.o funcs.o 02/06/17
[/root] >> swlist -l product | grep PHCO_27141
PHCO_27141 1.0 cumulative crontab/at/cron patch


Any ideas on what may have caused the problem ?

Thanks

Hi Eddie,

May be the load was too high on the box due to multiple processes spawned by the cron. If you have Measureware installed, you can get the GBL_CPU_TOTAL_UTIL and GBL_PRI_QUEUE metrics.

Eddie,
Pete Randall explained how he got that problem in his post. Although his problem applied to at jobs, it may very well be applicable to your situation:
