[RESOLVED] Win2008R2SP1: STOP 0x44 in srv2!Smb2FreeResponseBufferForAsyncCall+0x1c
Status: Resolved
Final Update 110823: The hotfix will be released in the October timeframe (HTP11-10).
Update 110815: We will now proceed with building a private hotfix package. As soon as that gets approved, we will release a public hotfix under KB2552033. Stay tuned!
Update 110810: Another customer came in with this issue. Other customers confirmed that with the latest instrumented binary they are not seeing the issue anymore.
Update 110808: Sorry for having gone silent on this for too long... :$ Two more customers contacted me with this error. We are working very hard on a hotfix to address this. This is currently committed for HTP11-10. In the meantime, if you have this issue, please do contact me and create a case with us, so I can track the impact this problem has! Many thanks to all of you who contacted me on this.
Update 110721: We now have three additional customers running into this. We received dumps with tracing and instrumentation. Stay tuned for updates! :)
Update 110715: Yesterday, another customer came in through the SCCM TAP program. I've also provided the instrumentation and tracing instructions for this case. Fingers crossed! :)
Update 110713: Instrumentation of srv2.sys brought us closer to the root cause of the problem. We are now working on a new instrumented binary to follow-up on these findings. Updates will follow shortly!
