|Problem Description||Talend Administration Center (TAC) needs to be restarted frequently as it gets blocked after 1 hour.|
|Problem root cause||
There could be many causes for this performance issue. It is important to know:
To get the TAC technical log, do a thread dump at the moment of the performance issue.
|Solution or Workaround||
Per the online document (Recommendations about environment and configuration for the Talend Administration Center) you should look at the values of these three parameters:
Note: You can locate the configuration.properties and the quartz.properties files in the Tomcat8.0\webapps\org.talend.administrator-6.2.1\WEB-INF\classes folder.
Increasing these values can be done incrementally, and it depends on the value of MAX_CONCURRENT_TASK_EXECUTIONS + MAX_CONCURRENT_PLAN_EXECUTIONS.
If hibernate.c3p0.max_size < org.quartz.dataSource.QRTZ_DS.maxConnections you will have problems, so it is important to ensure that the hibernate.c3p0.max_size > org.quartz.dataSource.QRTZ_DS.maxConnections.
You will need to restart the Tomcat / TAC for the change to take effect. After changing the values, the TAC should behave well and stop crashing.
