recently my ultra60 gave an error saying could not start up another process
or something similar,
and in /var/adm/messages it said that tmp was full but it was only 20% full
but had thousands of zero length files that a cron job was duming into
there. I rm the files and everything seemed to be working fine. Is there a
limit to the number of files in the /tmp dir?

What did 'df -e' tell you?

Yes there is (assuming you're using the default of a tmpfs filesystem
for /tmp). It's mentioned somewhat in the man page..

# man tmpfs
File Systems tmpfs(7FS)
[...]
Another constraint is that the number of files available in
a tmpfs file system is calculated based on the physical
memory of the machine and not the size of the swap
device/partition. If you have too many files, tmpfs will
print a warning message and you will be unable to create new
files. You cannot increase this limit by adding swap space.

Its tmpfs, Rolfie.

But you can do so by patching tmpfs_maxkmem in /etc/system.

The "limit on inodes" is really a limit on the amount of kernel memory
used to store "inodes", directory entries, and symlink targets. For
the benefit of statvfs(2) the amount of kernel memory used and the limit
are converted into an inode count by dividing by the amount used by
a regular file with a shortish name. This is what "df -t /tmp",
"df -e /tmp" etc. displays.

The other thing to bear in mind is that this usage and limit applies
to all existing tmpfs filing systems combined. In Solaris 8 or later,
for example, "df -t /tmp /var/run" will show the same inode statistics
for both filing systems.
