Hi,

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.

Thanks.

Hi Matt,

You're right! There isn't a lot but I did come across this from Microsoft...

Hope that helps.

Best regards

Take a look at Amit Banerjee's write-up on that wait type. It might be a less than optimal measure due to how it accumulates artificially.
