Could you enable cifs debug message logging and retry, appending the 
corresponding section of dmesg output to see if we can narrow down which 
call is running out of memory?

"echo 3 > /proc/fs/cifs/cifsFYI"   (enables informational messages, and 
logging of cifs return codes)
then
"dmesg" (or equivalent) after the mount.
