Got minus one from a read call

[Bi...@cox.com]

When I am executing a bulk load of data to Oracle, I intermittently
receive the following. This junit test created 47 accounts before
failing. If I run it again it may fail after creating 30 accounts. Has
anyone seen this before?  It appears that it is failing to create a
connection pool. 
Thanks for any help!
