Folks.
I am attempting to solve a very deep file system problem we are experiencing, and in doing so I am digging into the OSX source code published at opensource.apple.com
- The machine I am testing with is a late 2012 MacMini with 10.8.2, and during the failure, we see the error:
kernel[0]: smb_iod_sendrq: TRAN_SEND returned non-fatal error 35 sr_cmd = ..(a whole variety)
Looking at opensource.apple.com suggests that 10.8.2 includes smb-583.8, but examining the function smb_iod_sendrq from the 583.8 source code reveals that the error message is just :
smb_iod_sendrq: TRAN_SEND returned non-fatal error %d
ie. it doesn't suffix the "sr_cmd=" string
However, if you look at older versions of SMB, you will find the exact error message (including the sr_cmd string, included in smb-551 and some older versions.
From this I can only conclude that the 10.8.2 OS which we are testing with does NOT use smb-583.8 as the opensource.apple website suggests.
Could anyone comment on this ?????
For anyone interested, we are seeing a 100% repeatable situation where our application can essentially stall the entire SMB client environment to the point of failure, even after our app is quit. All our app does is read and write some files (at the same time).
Fails 100%:
- MacMini late 2012, SMB connection to another MacMini Server
Fails 100%:
- MacMini late 2012, NFS connection to Isilon Storage
Fails NEVER
- MacMini late 2012, AFP connection to another MacMini Server
Fails NEVER
- MacMini mid 2011 any storage, any protocol
Interestingly the Isilon NFS failure also shows error 35 (EAGAIN - resource unavailable) so this problem is not specific to SMB. Interesting that AFP never, ever fails, and mid 2011 Mac Mini with same OS. never fails.
Been going around in circles for 2 weeks on this, tried everything. It just seems our sequence of file calls takes down SMB or NFS, but ONLY with these new late 2012 Mac Minis..... wierd
Any ideas ?
Thanks
