Tomcat 4.1.24: No More OutOfMemory Errors

I know I'm probably jinxing myself, but I'm going to say it anyway. I just checked my catalina.out file (a.k.a. Tomcat's log file) and I haven't had an OutOfMemory error since I upgraded to Tomcat 4.1.24. I was getting them all the time with Tomcat 4.1.18. Hopefully you've seen the same stability increase. I'm sure this site will crash with an OutOfMemory error as soon as I finish this post! ;0)

Update: I send a message to Keith to verify that Tomcat hasn't crashed since Saturday night. Here is his response. 

The cron job hasn't had to restart it, and there are no out 
of memory errors in the log.  I can't find any sign that it
failed since then.

Sweeeeeettt!!

Is this on Win2K? How do you specify the JVM mem settings and have them actually work when firing up Tomcat. I put them in my catalina.bat file as the CATALINA_OPTS variable, but they don't seem to work. Linux it works fine for me.

Nope, it's on a Linux box where this site is hosted. I haven't had to change any memory settings when running on Windows.

Wait... I use tomcat-4.1.24-LE-jdk1.4 and jdk1.4.2 , but Tomcat will throw a java.lang.OutOfMemoryException. WhetherI edit my catalina.bat or not, it still doesn't work. I set CATALINA_OPTS=-server -Xms256m -Xmx512m -Xincgc but failed. I run in win2K OS. The same configuration in Tomcat4.1.18 will work. Please help me , thanks very much!

When I was having OutOfMemory errors, it was because I was running on a hosted Linux box, and some other users were using up all the memory. If 4.1.18 works fine, I don't know what to tell you.
