Supplementing the answer already given by Charles; Supposing that your tomcat process is running as user tomcat, you can use the following form of "ps" to show per-thread information in Linux command window: ps -fLu tomcat Additionally, you can do "kill -QUIT tomcat_process_id" from the command line to get your Java virtual machine to dump Tomcat thread information into the log file (it'll show what each of the threads was doing at the time when the kill command was run -- and this will not stop the tomcat server; all processing will continue normally). Data from the above two can be combined, however "ps" shows the thread ids in decimal numbers (LWP column) whereas the thread dump contains thread ids in hexadecimal (nid= element), so a conversion is needed to correlate the data. -- ..Juha --------------------------------------------------------------------- To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
