connections.tdb keeps getting corrupted. v2.2.1a

[MCCALL,DON (HP-USA,ex1)]

Hi Melvin,
We have a number of people on the list experiencing this problem - so far
all the reports I have seen involve HP-UX os'es, BUT, they range all the way
from 9.05, 10.20 to 11.00...  I'm trying to create an environment where I
can dup the corruption.  I'd be very interested if people could check their
logs to see if any NON-HP-UX platforms are being affected.
Two things you might try before backing down to a different version:
1. if you are using 2.2.1a, make sure you compile it WITHOUT mmap support.
we KNOW that mmap is going to fail
on HP-UX; the CVS version has a new smb.conf parameter, use mmap = no (no by
default on an HP-UX system) that will allow this to be configured.
2. make sure that your nflocks is plenty big (1024 or better) in your
kernel.

I'll post on the list if I get any further with this corruption issue, in
the meantime, ANYONE else out there experiencing these types of issues,
please let us know.

Thanks,
Don

I noticed another person having the same problems, does anyone have any 
ideas? Should I backout to another version?
