This was probably due to limits of your JVM. When we are getting Components
from a pool, Excalibur (used by Cocoon) will create new instances of the
Components when needed. If the JVM cannot create a new Component, then it
will throw an exception, and you will see the error message above.

This is usually associated with the Datasources code. The bug should be
fixed in the next release of Avalon. DataSources do not create new instances
of Connections, so a pool will wait indefinitely or until it is interrupted.
In that case, the lock is reset, and opperations will continue.

This is a warning message dealing with the Lock class used in Excalibur.
It is telling you that due to outside constraints, the pool caught an
IntrupptedException.
