ok I've got more info now :)

where RSS is the 'resident set size' TSIZ is the 'text size Kb' VSZ 'virtual
size in Kb'

I've also found that if I launch smbd from a csh script with
'limit datasize 20M' it will crash. I think that it may have something to
do with the name mangling cache as the following log message does not make
sense to me:

name_map_mangle( minfo.exe, need83 = FALSE, cache83 = TRUE, 6 )

samba decides that each opened file does not need name mangling and then
goes ahead and sets cache83 = TRUE ... is that logical?

I read though all the current bug/patch submissions and nothing seemed to
point here ... I tried turning off name mangling but I could still crash
the system and now people have arrived at work ( I have a ~1hr window to
work with in the morning).

does it sound like I'm chasing a ghost? csh suggestion came from someone
on freebsd-questions who thought I should do a crash dump (trace) of smbd
which is what I guess I'll do tommorow morning but this is definately
getting complicated!

just to reiterate that this is occuring on FreeBSD4.1-Release with a recent
version of samba-tng (obtained through cvs).

thanks,
