I'd start with the catalina.out log followed by the jira logs.

Location of the first depends on your os and how you configured your JIRA to work (stand alone or server). The second is in {JIRA_HOME}/log

i found following 3 error in the log files, is it familiar to you...

could you confirm which one is the reason:

Caused by: com.atlassian.jira.exception.DataAccessException: org.ofbiz.core.entity.GenericDataSourceException: Unable to esablish a connection with the database. (Communications link failure

That usually means a problem with your database connection - check the networking - routes, downtime, slowness etc.

As Nic says. In addition you can set a "validation-query", as per https://confluence.atlassian.com/display/JIRA/Surviving+Connection+Closures, which will allow it to get past little glitches.

However better to deal with the underlying problem.
