Hi, recently we caught w3wp crash on one of our Azure VM (West Europe) after last ASP Web API update.
Both of VM have Windows Server 2012 R2 with IIS8, same settings and applications. One of them located in West Europe, other one - East Australia. We also have traffic manager. Its routing method is perfomance.
When West Europe tries to execute any request we get event 1000 in event log:
Faulting application name: w3wp.exe, version: 8.5.9600.16384, time stamp: 0x5215df96
Faulting module name: unknown, version: 0.0.0.0, time stamp: 0x00000000
Exception code: 0xc0000005
Fault offset: 0x00007ffbf8776b8a
Faulting process id: 0xf18
Faulting application start time: 0x01d16b1fbb83993e
Faulting application path: c:\windows\system32\inetsrv\w3wp.exe
Faulting module path: unknown
Report Id: ff7ed046-d712-11e5-80d8-000d3a2252b3

Faulting package-relative application ID:
We tried to recycling application pool settings but it didn't help.
But when we disabled West Europe endpoint in traffic manage, application started to proceed requests correctly. East Australia continues working like correctly with and without enabled West Europe.
We totally run out of ideas. Please, could somebody help?
