Mount_smb: Mount failed: Not enough memory

I am trying to mount several remove file systems (6 to be exact). When I
try to mount the fifth one I get:

Mount failed: Not enough memory

Who’s doesn’t have enough memory and what can I do to adjust it?

Sin in says I have 27 MB left in the system.
I am running :
Proc32 4.25J Sep 9, 1999
Tcpip 5.00X Jan 28, 2000
SMBfsys 1.30I Dec 7, 1999

and mount_smb is Dec 8,1999 35409 bytes long.
