java.sql.SQLException: Connection is closed error in CAP Java application

113 Views

We are facing a random issue with Java's Hikari Pool. All of sudden Java app starts giving java.sql.SQLException: Connection is closed error. Only restart of Java fixes the issue, otherwise it remains stuck and keep throwing errors. It seems like it is not able to open new connection to Hana. This issue is not certain. It sometimes occurs twice a day and sometimes after few weeks.

Please find the attached Java logs and maven dependency tree files.
