You can use the command "padb -aQ" to show you the message queues for your application, you'll need to download and install padb then simply run your job, allow it to hang and they run padb - it'll show you the message queues for each rank that it can find processes for (the ones that haven't exited). If this isn't any help run "padb -axt" for the stack traces and send the output to this list. The web-site is in my signature or there is a new beta release out this week at http://padb.googlecode.com/files/padb-3.2-beta1.tar.gz Ashley. -- Ashley Pittman, Bath, UK.
