CIFS: dir -> long delay or Error in dskattr: NT_STATUS_IO_TIMEOUT
my problem occures on a 151a server with a large filesystem (12 TB) exported via sun-cifs. When doing a simple "dir" from a windows mount or a linux or even local smbclient connection I get most of the times a delay of about 20 seconds or sometimes an NT_STATUS_IO_TIMEOUT. Sometimes after a first "dir" the next "dir" gets an instant answer. The problem does not appear with a small filesystem on the same server.
If I use the samba-server instead of the sun-cifs-server, there is no such problem.
Any hints for me?
