[New-bugs-announce] [issue13335] Service application hang in python25.dll

[Chandra Sekhar Reddy]

New submission from Chandra Sekhar Reddy <sanch09 at ca.com>:

Service application hanged in python25.dll, below are the environment details.

Operating System : Windows server 2008 R2 (Virtual Machine) Application Type : Service Application

We have got the process dump from the customer environment and after analyzing the dump using the Windbg tool.

Below is the status of the 4 running threads.
 
 Last error for thread 0:
 LastErrorValue: (Win32) 0 (0) - The operation completed successfully.
 LastStatusValue: (NTSTATUS) 0 - STATUS_WAIT_0
 
 Last error for thread 1:
 LastErrorValue: (Win32) 0 (0) - The operation completed successfully.
 LastStatusValue: (NTSTATUS) 0 - STATUS_WAIT_0
 
 Last error for thread 2:
 LastErrorValue: (Win32) 0 (0) - The operation completed successfully.
 LastStatusValue: (NTSTATUS) 0 - STATUS_WAIT_0

Last error for thread 3:
 LastErrorValue: (Win32) 0 (0) - The operation completed successfully.
 LastStatusValue: (NTSTATUS) 0 - STATUS_WAIT_0
 
 But as part of the hang analysis the command "!analyze -hang" shows
 some problem with thread 1
 
 Probably caused by : python25.dll ( python25!PyList_New+62 )
 
 03dff250 1e072c5b python25!PyFuture_FromAST+0x873
 03dff25c 1e073307 python25!PyFuture_FromAST+0xbcb
 03dff264 1e07332e python25!PyObject_GC_Malloc+0x67
 03dff270 1e081502 python25!PyObject_GC_New+0xe
 00000000 00000000 python25!PyList_New+0x62

Thanks,
