This looks like a problem specific to Windows 7 or above. Quick tests on
my test machines shows that cifs attempts to connect, times out,
attempts to reconnect and gets -EHOSTUNREACH in case of both Windows
Servers and Samba Servers. This is the expected behavior.
OTOH, this sounds like a problem related to an error due to the Windows
server being unable to allocate from the system nonpaged pool (seen in
the past). Do you see anything that is related to the error in Windows
Event viewer?
Hi,
Yes, you are correct--
The server was unable to allocate from the system nonpaged pool because the
server reached the configured limit for nonpaged pool allocations.
Justin.
