Ok so here is my problem, I recently updated my server and change some jsp files which are used to do automatic announcements. The crontab has all the .sh files listed within it and the .sh files run the jsp files to display the announcements.
After I finished updating the jsp files, I rebooted the server and ever since then the announcements have stopped running. I can run the .sh files via putty manually and they work perfectly fine so the changes I made to the jsp files are not the problem.
I did some research before posting here and I checked the syslog for cron entries. Up until the point I rebooted my server the cron service was running as it should. Since the reboot there has been no entries in the syslog for cron.
I've tried rebooting the server again, I also tried restarting the cron service, I also even tried stopping the service completely and starting it again with no effect. I can't figure out why the cron service would suddenly stop working as nothing to do with cron or any of the operating files were touched during the update of my server.
Does anyone have any suggestions as to why it may have stopped working? I'm using Ubuntu Server 11.10
