[JBoss-dev] [ jboss-Bugs-657311 ] Resource Contention - Leaking Handles
Bugs item #657311, was opened at 2002-12-21 16:16 You can respond by visiting: https://sourceforge.net/tracker/?func=detailatid=376685aid=657311group_id=22866 Category: None Group: None Status: Closed Resolution: Invalid Priority: 5 Submitted By: Dennis Cartier (dcartier) Assigned to: Nobody/Anonymous (nobody) Summary: Resource Contention - Leaking Handles Initial Comment: I have noticed some odd files appearing in the /tmp directory of my Linux JBoss machines. They are all named ddtbX.tmp Eg. ddtb48340.tmp ddtb48349.tmp ddtb48358.tmp ddtb48367.tmp ... When I check the output of lsof, it appears that close to all of the java processes running each have every one of the ddtb files open. This quickly adds up to thousands of open files. Each one of the ddtb files are 0 bytes long, so there is not even anything in them. I have tried deleting them while JBoss reamins running, no ill effects were observed, but lsof still shows the java process having them open even after they are gone. It appears to be only under load that the files are created. Idle servers do not seem to generate these files. I am just worried that over a period of time, this will cause the JBoss servers to eventually fail. Can anyone shed any light on this? Particulars: JBoss 3.0.4 Tomcat 4.1.12 Debian Stable Linux Kernel 2.4.19 Sun 1.4.0_02 JVM -- Comment By: Dennis Cartier (dcartier) Date: 2003-01-19 11:54 Message: Logged In: YES user_id=673615 I found the problem in my code.
