Connection Reset when Accessing the Database

Problem

Errors/failures in the Git Integration for Jira application are seen sporadically. Automatic reindexing may stop.

Diagnosis

Jira admins will see a message similar to the one below in the Jira log: /application-logs/atlassian-jira.log:

2019-08-04 07:11:11,173 Caesium-1-1 ERROR ServiceRunner     [c.a.s.caesium.impl.CaesiumSchedulerService] Unhandled exception during the attempt to execute job 'com.bigbrassband.jira.git.jiraservices.jobs.RevisionIndexJob'; will attempt recovery in 60 seconds
com.atlassian.jira.exception.DataAccessException: org.ofbiz.core.entity.GenericDataSourceException: SQL Exception while executing the following:SELECT ID, JOB_ID, JOB_RUNNER_KEY, SCHED_TYPE, INTERVAL_MILLIS, FIRST_RUN, CRON_EXPRESSION, TIME_ZONE, NEXT_RUN, VERSION, PARAMETERS FROM dbo.clusteredjob WHERE JOB_ID=? (Connection reset by peer: socket write error)

Cause

When a database server reboots or a network failure has occurred, all connections in the database connection pool are broken, and JIRA would normally need restarting to recreate those connections. See Atlassian’s Surviving Connection Closures documentation.

Solution

See Atlassian’s Connection Reset when Accessing the Database article.
