The output was nothing. How do I capture it into a file? The development team here asked me to take a thread dump and I told them to check the logs. Can somebody please help more here? I want to save the thread-dump to a file. devUnix View Public Profile View LQ Blog View Review Entries View HCL Entries View LQ Wiki Contributions Visit devUnix's homepage!
