How is the "application" invoked?  Is it a "service" (servlet instance, RMI
object-mediated, etc.), i.e. does a core-component run forever and spawn
helpers to handle requests?

I'd guess that you are slurping output from an external process'
STDOUT/STDERR and the process-control API noticed that one or both sides of
the conversation broke the underlying conduit (the pipe) between the
processes.

I'm running an engine with 15 databases, with fair amount of load. Every
4-5 days I'm getting error like this from the java side and the
application stops working (and wont come back unless I restart) :

Does anyone know what this is about ?
I'm using Red hat Enterprise, and all the correct JDBC drivers etc.
