In the past week we've twice had a log shipping restore job hang with a wait type of PREEMPTIVE_OS_GETPROCADDRESS.
We're using SQL Backup so I've raised the issue on the Red Gate support forums. My question here is, what does this wait type actually mean? I can't find it listed in BOL, and an internet search returned very little, other than a few people having issues with third party backup tools.
If anybody can shed any light on what this wait type means that would be greatly appreciated.
