The problem is that your OS is running out of resources. Have a
look in the /proc filesystem:

        /proc/sys/kernel/file-max: maximum number of open files
        /proc/sys/kernel/file-nr:  current number of open files
        /proc/sys/kernel/inode-max: max. number of active i-nodes
                                   (avg 3 per file)
        /proc/sys/kernel/inode-nr: current number of active inodes.
You can increase these limits (1024 and 3072 by default) as follows
        # echo "2048" > /proc/sys/kernel/file-max
        # echo "6144" > /proc/sys/kernel/inode-max
The 'no more processes' puzzles me a little, as Linux doesn't have
a limit on processes as older UNIXes used to have. I guess the message
is caused by the lack of file handles or inodes.

Because it's not a Samba problem. The system logs (usually somewhere
in /var/log or /var/adm) would be a better place to look.

Because it's a tad heavier on resources (but also a lot faster).
