I've seen the error a couple of times, but I don't have a fix for the issue yet as I don't have a reliable way to reproduce the error. If you have an easy way to reproduce the bug, I'll see if I can figure out a fix. -- Ryan Harper Software Engineer; Linux Technology Center IBM Corp., Austin, Tx ryanh@us.ibm.com
