Yep, I was not out of the woods yet...
This is a tough issue to reliably test. It looks like in addition to
the soft and hard limits you can set in the limits.conf, there is also a
kernel-limit to cap it all off. root can override that limit, so I also
added:
ulimit -n 2048
in the start section of /etc/init.d/xinetd (and perhaps a similar
modification would be done to famd's init script if not using xinetd).
This *seems* to be working better now. But only time (and end users)
will tell.

I dug in a bit more.
It's been a while so forget some of the details.
if I put some thing like
ulimit -n 8196
in the startup script it last a little longer.
Probably gets another 100 files monitored before failing
Sent bug report to debian and to fam list.
No response :(
Pretty sure the problem is in dnotify or how fam works with dnotify.
There is an array in the dnotify part of fam. I raised from 1024.
That had no affect.
I rebuild fam without dnotify support.
It works fine but fam becomes a real hog.
When run that way fam monitors all files as the calling user.
Currently running without fam.
Restarting fam will keep you going but any previosly monitored files
will no long be monitored.
I wouldn't do it in production envronment.
