Hi there everyone!

I'm using Samba 2.0.5a-19990721 on a RedHat 6.0 machine with Linux kernel
2.2.12. My system generally works fine, however recently I've had some
complaints about some files being corrupted. The latest and best-handled
to enable a debugging happened at around the same time. Both clients were
using Windows95 OSR2 machines with Excel 97 SP-2. Two users reported the
problem and they were using separate machines. Nobody was "messing around"
with the server (though I noticed SIGHUPs in the log files!!! I don't know
why they were there, maybe someone could explain why Samba gets regular
SIGHUPs and if these could cause damage?).

Here is the log of the first user. Please pardon the excessive
log-quoting. I'm hoping to help you all help me out. :-)

NOTE: Please cc your reply to me <jijo at leather-collection.com> because I
cannot subscribe myself to the list. I will, however, regularly check the
archives on the web for responses to my query. Thank you very very much!!!
