When Tomcat is shut down and I run a ps -ef no java threads are displayed. Is there any way for me to go in manually and check if there are any threads are being held onto by Tomcat/Java, and release them?
Thanks. Denise -----Original Message----- From: Denise Mangano Sent: Monday, September 22, 2003 8:57 AM To: Tomcat Users List Subject: RE: Cannot run Tomcat as new user [Was: Urgent! Cannot start Tomcat - java.lang.OutOfMemoryError] After compiling and running some offline sample java programs, it seems unlikely that the problem is with the JVM. If it were I shouldn't be able to run any java programs under non-root users, but I can. The problem still only appears to be when starting and stopping Tomcat as a non-root user. I need to find a resolution to this asap. I am wondering if there is any way that if I am stuck with starting Tomcat as root, is there anyway it can be started as root, but then spawn off child threads as a non-root user (i.e. the way apache does it..) Thanks in advance. Denise -----Original Message----- From: Denise Mangano Sent: Friday, September 19, 2003 4:51 PM To: Tomcat Users List Subject: RE: Cannot run Tomcat as new user [Was: Urgent! Cannot start Tomcat - java.lang.OutOfMemoryError] My Tomcat is not running on port 80. I have Apache running on port 80 communicating with Tomcat via mod_jk (Apache starts up fine). Also I am not using IPTables - I have relied on our network firewall for protection. I think Filip is on to something with the JVM... I am posting to Linux boards right now...

Cannot start Tomcat - java.lang.OutOfMemoryError] I forget if you've said or not, but are non-root users allowed to priveleged ports? Which is what Tomcat would do if you've changed it to port 80. Forgive my non-linux background, but perhaps you were using an IPTables solution to work around this limitation I vaguely and poorly remember, and because your machine crashed, those settings are gone.
