The following error can be found on atlassian-stash.log:

ORA-02391: exceeded simultaneous SESSIONS_PER_USER limit


This means your Stash instance is opening more connections than defined on your SESSIONS_PER_USER on your Oracle database


Just as defined on Stash config properties - DB Pool, the default value for db.pool.partition.count is 4 and db.pool.partition.connection.maximum is defined as 20 by default, the maximum number of connections to be established by Stash will be 80 and the minimum will be 16 - as db.pool.partition.connection.minimum defaults to 4.

You could either:

  • Adjust SESSIONS_PER_USER to accommodate your current db configuration.
  • Adjust your stash-config.properties to accommodate your SESSIONS_PER_USER
