Abhinandan Prateek commented on CLOUDSTACK-1805: ------------------------------------------------ There could be two aspects to this issue: 1. Assuming this is a issue with connection pool; I reviewed all the settings that we are doing and these look fine. We can try to set the following parameter to make the checks even more stringent for idle connections: testWhileIdle=true : This is one param that can make checks for idle connections, we should try setting in db.properties to true. 2. It is also possible that we have some where in code that we do not release a borrowed connection. This connection will expire in the app itself. For removing such connections we should also try out the following params: removeAbandoned=true removeAbandonedTimeout=18000000 # 30 minutes > com.mysql.jdbc.exceptions.jdbc4.CommunicationsException seen after long time > of inactivity resulting in not being able to log in to thr management server. >
