this is what Rainer talked about :
Data Mover panicked when a Windows 7 client connected to a CIFS share through a Riverbed WAN accelerator with the SMB2 protocol enabled. The Riverbed WAN accelerator sent an SMB2_IOCTRL request compounded with SMB2 commands which the Data Mover did not decode correctly. DART panic/fault message:
>>PANIC in file: /disks/NSG_Maint8/6.0_ build
_nfs_env/Dart/server/src/kernel/include/stream.hxx at line:
1119 : datab::freeRef: db_ref <= 0 Panicking Processor: 3
The stack trace showed:
245ea0: 0xdcc4fd _ZN14smb2_threadCtx7processEP4msgbi+0xf57
245f20: 0xdee8d6 _ZN13smb_threadCtx5startEv+0xc4c
245fd0: 0x155263 Sthread_startThread_internal+0x7
The Data Mover now properly handles compound SMB2 requests received in this manner.
Fixed in version :
DART 188.8.131.52 had some issues and was pulled back, but will be released again soon.
