Hi, we use TomEE 7.0.4 productively in a Cloud Foundry environment. JDBC connections are only used via JPA (eclipselink). Usually after one day or so uptime we see these errors:
org.apache.tomcat.jdbc.pool.PoolExhaustedException: [http-nio-8080-exec-10] Timeout: Pool empty. Unable to fetch a connection in 30 seconds, none available[size:2; busy:2; idle:0; lastwait:30000].", We did not specify pool size anywhere and I believe standard pool size is more like 100 than 2. What could cause this extremely small pool size? Is this somehow negotiated with the JDBC driver and/or DBMS? We use postgresql 9.4.1212 jdbc driver for a postgresql server on version 9.6. Any ideas greatly appreciated. Many thanks! -- Sent from: http://tomee-openejb.979440.n4.nabble.com/TomEE-Users-f979441.html
