Okay, a simple answer from a simple mind: Check that you are closing resources in your java code appropriately. Don't rely on garbage collection!
Are you closing any files opened by your Java code? Are you always closing your jdbc SQL statements/result sets, etc...? Are you closing your Oracle connections? Are there too many open connections? Are there any blocking db locks? I have had this problem before where my db connected application had not committed it's transaction and ended up hanging tomcat. Always check to see that your resources are being released and not halting other requests. Since you're using Oracle, check the V$SESSION view to make sure you don't have more active connections than you believe you should have. Check the v$session_wait to make sure nothing is blocked. I'll bet a t-shirt that it's a db problem. If you can't get to those views, ask your friendly dba to help. >>> [EMAIL PROTECTED] 05/28/02 07:24PM >>> Here, we have the same problem!!! What can it be? Our configuration: - SunOS 5.8; - Solaris 8; - Dual UltraSparc 400Mhz; - J2SE SUN 1.4; - Tomcat 4.0.3; - We are using -Xmx1024 -Xms512; - MaxProcessors=250, MinProcessors=10, acceptCount=250; - Oracle Thin JDBC; PS 1: we are not having the "classic" OutOfMemory error. Tomcat just hangs-up with no reason. PS 2: We already used OptimizeIt to tune the application. PS 3: Tomcat stops even with a low rate of usage.
