Wait indefinitely PREEMPTIVE_OS_GETPROCADDRESS
I installed 3 instances of Red-Gate Backup 22.214.171.124. Then applied patch 126.96.36.1994 to all instances.
I observed this weird behavior:
Red-Gate Backup PDB1 is running OK.
Red-Gate Backup PDB2 and PDB3 always hung. The activity monitor showed a wait type of PREEMPTIVE_OS_GETPROCADDRESS on the SQL Backup session. I noticed there is no other logs stored in C:\Program Files (x86)\Red Gate\SQL Backup 6\.
I'm really not sure where to go from here. Please help.
