frozen sessions
Posted in 2010
Can somebody tell me what a session in a "cond wait PC_I hash" condition
mean?
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.
