Subject Socket Exceptions
Date Thu, 06 Feb 2003 15:27:51 GMT
I'm trying to get an idea of the root cause for this exception, does anyone
have an idea?  Could it have anything to do with dropping connections, users
pushing stop or the number maxProcessors?  I haven't really got an idea.  I
am not using Apache at the moment, just straight Tomcat with the Coyote
connector.

Thanks,
John O'Neill
