my jira version is 4.4.1.
the jira has been running for more than one year,so there are many datas in jira.
today,jira service is suddenly stopped.so i have to start the service. but after a while it stopped again.
then i once again start the service,and this time jira is successfully started.
i tried to search error messages in atlassian-jira.log , and couldn't find any message about "OutofMemory".
so i was confused about it.
