[RESOLVED] Win2008R2 SP1: dfsrs.exe crashes in dfsrs!JPrintfFormatValue_unsigned_short,FrsStringImpl_unsigned_short,char___+e

  • Artikel

Status: Resolved.

Update 120301: Private is approved, Public is scheduled for REL12-04, to be released mid-April.

Update 120217: The private is ready!

Update 120215: other customer came in hitting this, private is in the works. This should be available shortly. :)

Update 120208: we have two more customers hitting this. Currently discussing the issue with Engineering.

This morning Erik of our Domains team asked me to take a look at this dfsrs.exe dump. It resembles an issue we've come across in the past, but which was never resolved. Those are the issues I like best! ;) So, we don't have too much info on this yet, but I just wanted to get an idea if there are more people hitting this. If so, please send me a message and create a case with Support!

Some info:

It looks like this is related to some backup, based on the DFSR Writer being involved. Stay tuned for more info!
