Cron job to restart tomcat

[Bukira]

Hi All,

We are having issues with our tomcat crashing weekly if not twice a week, we are having to manually restart it with

jssutil rt

I am trying to put this into a cron job so that it can be started every night, but its not working

i tried in the root crontab

0 0 jssutil rt >> /var/log/cron.log

but no joy it doesn't run

I have tested cron by putting in an echo line and a date line and both work well,

I also tried to make a shell script with the commands in and then run that as such

0 0 /Library/Scripts/RestartTomcat.sh >> /var/log/cron.log

but still no joy

Anyone any ideas?

Wasn't cron depreciated for launchd on osx?

Ben.

I always use crontab -e Comman and then add the Task, Don't use it in OS X but it says it works

Cron was deprecated in 10.5 I believe. use launchd.

and it works fine at running my script every 60 seconds

Criss,

What are the tomcat issues that you are seeing? We were having a lot of issues a month back that would require manual restarts a few times a week. We've made some changes since, and I've not had any issues.

Thanks
Allen

Use launchd instead, but I gotta ask, why do you have to constantly
restart TomCat?

What version of the JSS are you running? There was an issue in 8.1 that was
causing my JSS to lock up almost daily, the 8.22 update fixed the issue.

There was a log purge/deletion bug in 8.21 which caused Tomcat to go out to lunch (had it on two servers, got JAMF Support involved/duplicated the problem and fixed it in 8.22). Recommend that the original poster look for the source of the issue of why Tomcat is crashing, updating their JSS if necessary...
