Well... two things.... 1.1.4 is a much better version than 1.1.3 and I  
would recommend using that version if at all possible.  Be sure to read  
the release notes when upgrading because there are some changes the  
effect the webapp (in fact it may be the case since you are building  
from CVS and I'm not EXACTLY sure which version you are having similar  
problems)

Second thing is... What exactly do you mean by 'crash' if you mean  
exceptions I would appreciate seeing the logs.  (I have had some  
exceptions related to MBeans that have prevented Tomcat from restarting  
because I didn't remove the context if server.xml - the solution for  
this is described in the Known Issues section of the release notes  
available on Sourceforge).  If you mean the JVM itself crashes, that is  
more serious.  There are two causes I've seen.  One is a JVM bug..  
There is one that 1.1.3 exercises.  1.1.4 avoids this.  The second is a  
problem with the JVM on the platform you are using.  I don't know what  
platform you have, but I've seen crashes with 1.4.2 related to compat  
problems and such.  Can you please let us know what version of Linux  
you are using?
