Subject Re: Tomcat 4.1 stops responding on RH9
Date Fri, 18 Jun 2004 09:08:35 GMT
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
