Share modes problems

I'm having a problem with share modes (at least I think it's share
modes) on my samba server. The problems only seem to have
manifested themselves since I updated to samba 2.0.0. This has
coincided with an upgrade to our system, so it is conceivable that
the problem may be with that, but I think it more likely that it is to
do with samba (since errors are reported in the log files).
One of the guys who uses the system has noticed that he's unable
to save word/ppt docs from time to time. This happens when he's
working on word/ppt docs on a share. When he tries to save the
doc, ater some time windows reports something to the effect that
the disk is full and or that there are too many files open. The
problem is not reproducable, but only happens from time to time
(say every few hours).
I've had a look at the samba logs for his pc and this is what
happens at the time that he has the error.

Here's some more errors that have arisen in his logfile.

get_share_modes: malloc fail!

I don't know much about share modes, but I'd guess that the
system puts a lock on the doc when he starts to edit it. Then when
he saves it, samba attempts to remove the lock, but it may already
have been removed, and, consequently, the number of share mode
entries becomes more and more negative.
The server is operating in user level security mode. The share that
he's working on is a shared resource. The share can be accessed
by a number of users. The share has "force user" and "force group"
enabled, so all the users can view/edit each others documents.
System - samba 2.0.0, solaris 2.6, compiled using egcs 1.1.
I was wondering has anybody else observed such behaviour.
