frozen sessions

Posted By: JAMES GEDYE

Can somebody tell me what a session in a "cond wait PC_I hash" condition mean? I've never seen a session in this state before.

I have multiple sessions that are all stuck at the same place.

The statements are all called from stored procedures. The last one executing (spil_send_mail)

only inserts into a table, but that's where all of the sessions appear to be stuck.

This is on Redhat Linux 5
