[RESOLVED] Win2008R2: STOP 0x27 in mrxsmb20!Smb2ReconnectOpen_Finalize+0x74

  • Article

Status: Resolved

Update 111206: After discussing this with our customer they agreed to accept the workaround of increasing memory for the impacted machines.

Update 110823: Finally I found the trigger for this STOP error: memory pressure. Further looking into this now to see if we can indeed trigger the problem this way.

Update 110706: We now have an instrumented binary in place to gather additional information.

My colleague Daniel is working on a STOP 0x27 in mrxsmb20!Smb2ReconnectOpen_Finalize, with the following stack:

 We have enabled Redirector tracing and currently we're awaiting a new dump including this tracing. Let me know if you also see this issue!
