IO error while logging

Mon, 14 Aug 2006 08:23:09 -0700

I'm seeing an intermittent error on one of our jboss servers. Every once in a while, something happens to the logging system, and every attempt to write to the log causes an exception (see below), which of course is of major concern to us.
So far, this is only happening on one box. I'm trying to narrow it down some more, but so far I don't have a lot to go on. Any suggestions would be most welcome. 



JBoss 4.0.1 with log4j 1.2.8
Java 1.5.0_05 on Linux
