Update c3p0 to 0.9.1.2 ---------------------- Key: HHH-3189 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3189 Project: Hibernate3 Issue Type: Task Components: core Affects Versions: 3.2.5 Environment: Tomcat 5.5, Hibernate 3.2.5, MySQL 4.1.11a-4sarge, c3p0 0.9.1 Reporter: Jean-Philippe Bouchard Priority: Minor Attachments: borked.txt I run a pretty busy site and every 24 hours or so, the system completely locks up and I have to restart tomcat. I investigated and the problem occurs in c3p0 which I use for my connection pooling. I attached a file containing the stack traces (obtained with JConsole) of some of the http processor threads when the system locks up. Using JConsole, I also tried to run softResetAllUsers() on the pooled datasource when the system is locked up and that fixes the issue as well. In the change log for c3p0 0.9.1.2, they mention a fix of a deadlock issue so I tried the new version and the problem doesn't occur anymore. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://opensource.atlassian.com/projects/hibernate/secure/Administrators.... - For more information on JIRA, see: http://www.atlassian.com/software/jira
