Hi all,

I am having problem where Tomcat 4.1.27 just stops after some random period of time. I am on RH9 and JDK 1.4.2. This seems to be the same problem reported earlier and a recommended fix was to set an environment variable LD_ASSUME_KERNEL=2.4.1. Can I simply put an "export LD_ASSUME_KERNEL=2.4.1" in my setenv.sh file?

Also, I have heard other recommended values, such as LD_ASSUME_KERNEL=2.2.5; how would I find out which one to use?

Hello.

Is this the same problem I also asked yesterday about in thread

"All threads are busy ... servlet status 75"

Somewhere I read about setting the LD_ASSUME_KERNEL to 2.2.5
But I also read somewhere that this didn't help
