It's a bad security practice, as it is possible to trick a Tomcat into running code on the server if there are apps you can upload data to.  Running code as root - you've handed the server to the attacker.

You should never run an externally facing service as root

Thanks for the reply Nic,

Follow up question: Is there any issue running jira from root user? I am running jira from root user only.

thanks

appreciate your reply

Your Jira system was unable to write to the disk, as the operating system blocked it.  If you've checked the permissions are ok (remember Jira should be running as a dedicated user, not root or a real human user), then check the disk space and anything else that might stop it writing.
