crontab problems

[Safir Safir]

Hello,

I have a problem on cron.
the date was modified on the server and since then the cron jobs does not start.System is HP9000 with HPUX11i ver1.

I stopped the cron deamon and restart it ,i verified all the permission,the writes everything is fine.i stopped all the cron and i created only one job and assigned it to root user .the job does not start and in /var/adm/cron/log i had the following :
> CMD: /usr/bin/date >> /tmp/ez.log
> root 22620 c Thu Mar 13 08:25:00 GMT 2008
< root 22620 c Thu Mar 13 08:25:00 GMT 2008 ts=139.

what is the ts errors? someone has an idea ,i didnt get an rc error???

thank you in advance

That looks like a perfectly normal cron log entry. Your command "/usr/bin/date >> /tmp/ez.log" was started at 8:25:00 with PID 22620 and completed at 8:25:00.

The question is, what does /tmp/ez.log contain?

Hello,

the ez.log file is empty nothing in it .Even i ran the cron that they are related to other users with no success. the log file contain 3 entries but with ts=11 .

so what do you think about it?

ts= means you got a signal.
In your case, signal 139-128 == 11

hi BR,

can you also post the output of:
ps -ef|grep cron

we want to know if the process is running.


also, the cron log file:
tail /var/adm/cron/log

Hello

Please find below the output of ps

> CMD: /usr/bin/date >> /tmp/ez.log
> root 29547 c Thu Mar 13 13:50:00 GMT 2008
< root 29547 c Thu Mar 13 13:50:00 GMT 2008 ts=11
> CMD: /usr/bin/date >> /tmp/ez.log
> root 29610 c Thu Mar 13 13:51:00 GMT 2008
< root 29610 c Thu Mar 13 13:51:00 GMT 2008 ts=11

even i restart the server and still the same error. the cron is running

ps -ef|grep cron gives the following:
ps -ef|grep cron

please advise

Hi,

your cron seems to run ok, as it starts your job and also registers that it has finished. But there is a problem with either /usr/bin/date or your computer.
What happens if you run /usr/bin/date from the command line? And does your syslog and mail to root not contain anything suspicious?

regards,
John K.

[Yogeeraj_1]

hi again,

Answer John's questions above and perform the test below:

- Modify your crontab entry such that log files output-showdate.crn and error-showdate.crn

e.g.
#*******************************************************************************
# min|hour |day |month|day |script
# | |of mo| |of wk|
#----|-----|-----|-----|-----|--------------------------------------------------
#*******************************************************************************
05 07 * * * /home/yogeeraj/showdate.sh 1>/tmp/output-showdate.crn 2>/tmp/error-showdate.crn
#*******************************************************************************
# END OF TABLE day0->Sunday day6->Saturday
#*******************************************************************************

what does these files show?

revert!

What's your real problem?

cron should be working. How many users have crontabs? How many work?

If it is only this one, don't use that shell any more.

Can you find a core file from that signal?
What does your crontab entry look like?
Can you use /usr/sbin/sh at all?

[Safir Safir]

Hello again

all crons for all users are not working ,
root,oracle,debit all users even the cron.allow is here and contaims all the users.

even i made a cron with

* * * * * /usr/bin/date >> /tmp/ez.log
for example

[Yogeeraj_1]

hi,

Will it be possible to post the content of the current crontab?


crontab -l


also, confirm that you can see the following message (or similar) in your /etc/rc.log
...
Start clock daemon
Output from "/sbin/rc2.d/S730cron start":
----------------------------
cron started
...

hi again,

Perform the following steps so that the problem can be isolated ($$$$#error in crontab entries or script not executable#$$$$):

Step 1. Create a new script
$ vi /tmp/script1.sh
#!/usr/bin/sh
echo $(date)
#End of script

Step 2. Save script and make it executable
$ chmod +x /tmp/script1.sh

Step 3. Edit your contab and delete all the current entries (assuming it contains only the lines that you have posted above)

Step 4. Add the following lines in your crontab:

#*******************************************************************************
# min|hour |day |month|day |script
# | |of mo| |of wk|
#----|-----|-----|-----|-----|--------------------------------------------------
#*******************************************************************************
* * * * * /tmp/script1.sh 1>/tmp/output-script1.crn 2>/tmp/error-script1.crn
#*******************************************************************************
# END OF TABLE day0->Sunday day6->Saturday
#*******************************************************************************

Step 5. Save and exit the crontab editor.

Step 6. monitor files:
/tmp/output-script1.crn
/tmp/error-script1.crn


Update us on the results after a few minutes.

kind regards

Hello Again,

It is done as you said

/tmp/error-script1.crn and /tmp/output-script1.crn are not created.

/tmp/script1.sh it is working from command line

cron is started
and this is the output of /var/adm/cron/log

< root 6847 c Fri Mar 14 12:15:00 GMT 2008 ts=11
> CMD: /tmp/script1.sh 1>/tmp/output-script1.crn 2>/tmp/error-script1.crn

>script1.sh it is working from command line

That would indicate the shell is working.

About the only other explanation is some evil process is sending kill signals to your shell, under cron.

[Yogeeraj_1]

hi,

There is definitely something 'weird' going on!

can you post the output of the following?
ll /var/adm/cron

e.g.

is it possible that a third parity programs is killing the cron process as oracle ???

BR

[Yogeeraj_1]

hi,

>is it possible that a third parity programs is killing the cron process as oracle ???

Not likely. It can only be a user script if it is indeed the case.

can you post the output of the following:
whereis cron
ll /usr/sbin/cron

e.g.
SRV2:>whereis cron
cron: /usr/sbin/cron /usr/share/man/man1m.Z/cron.1m
SRV2:>ll /usr/sbin/cron
-r-xr-xr-x 1 bin bin 40960 Aug 24 2006 /usr/sbin/cron

Hi again BR,

just guessing, but file permissions may have been changed or files may be missing.
I suggest that you look through the history files of the root user for commands like chmod, chown, rm and the like. Does anything there look suspicious?

regards,
John K.

[Dennis Handly]

>John: but file permissions may have been changed or files may be missing.

If this is the case, then "swverify \*" will do this check.

[Safir Safir]

hello there

all the permissions seems to be right

any suggestion

do u have any idea about the error code ts=11????

thank you in advance
BR
