[jboss-jira] [JBoss JIRA] Updated: (JBPORTAL-1401) Portal Unresponsiveness With Conection Pool Bottleneck

Portal Unresponsiveness With Conection Pool Bottleneck ------------------------------------------------------ Key: JBPORTAL-1401 URL: http://jira.jboss.com/jira/browse/JBPORTAL-1401 Project: JBoss Portal Issue Type: Bug Security Level: Public(Everyone can see) Components: Portal Security Affects Versions: 2.4.1 SP1 Environment: RHEL 5 Windows XP Reporter: Mike Millson Assigned To: Julien Viet Attachments: JDBCConnectionPoolTest.java, mgm-thread-dump.txt, portal-oracle-ds.xml Observed Behavior: When the connection pool is not adequately sized, the portal freezes. A thread dump shows that a single http connector thread holds the lock to java.security.Permissions.implies(Permission) and is waiting BlockingTimeoutMillis to get a connection. Almost all the other http threads are blocked waiting to aquire the lock to java.security.Permissions.implies(Permission). Apparently the thread waiting for a connection needs a connection to look up the permissions in the database. Expected Behavior: The portal should not become unresponsive. Portal 2.6 CR2 does not freeze up when the same test is run. I will attach the test case, thread dump, and datasource.
