http://issues.apache.org/bugzilla/show_bug.cgi?id=34373 Summary: Out Of Memory Exception Product: Commons Version: 1.0 Final Platform: PC OS/Version: Windows 2000 Status: NEW Severity: normal Priority: P2 Component: File Upload AssignedTo: [email protected] ReportedBy: [EMAIL PROTECTED] CC: [EMAIL PROTECTED] Scenario: Use FileUpload library in a servlet implementation for multipart request parsing. Launch stress test in order to submit a lot of Post Http request with many parameters and file to upload. Environment: Windows (2000 or XP) with Sun JVM or IBM JVM 1.4.x Problem: After few hours the server crash with an out of memory exception. The HeapDump of the jvm at the crash time shows that a lot of memory is still available in the java heap. This out of memory is due to an out of memory of the java native heap. Sample of exception message: [Signaling in VM: java/lang/OutOfMemoryError, message: JVMCI015:OutOfMemoryError, cannot create anymore threads due to memory or resource constraints] Cause and solution: The problem seems to be due to the File.deleteOnExit() call used in the DefaultFileItem class. This call is used in order to delete temporary file at the exit of the JVM. This call seems to create memory leak in native heap on Windows OS (We didn't test it on Linux or Unix) Moreover this is not usefull to let file destruction on exit of the jvm on a server. In order to delete temporary file created by DefaultFileItem, a cleanup method should be added, or a cleanup of the temporary files should be provided, but not the File.deleteOnExit() method. -- Configure bugmail: http://issues.apache.org/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug, or are watching the assignee. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
