I just tried again. This time, I found 2 Bs amongst 8 As, so not all write 
access from one machine got lost this time (still 3/4).

stat gives identical output on both pcs if both try writing. If only A tries 
writing, I could see that the file was not updated on B for a small amount of 
time (maybe the already discussed second). However I already had a situation 
where this update was not done for several minutes - but this seems harder to 
reproduce.

So, if you all allow, I would like to summarise here. From your comments I 
gather, this is not a misconfiguration of server or client by myself, is this 
correct? It seems, that maybe the writing may be related to a timing issue 
with ext3 time resolution, however this seems unlikely because I left up to 3 
seconds between each A and B write access and still found only As. Finally, 
I'm the first one encountering this problem and reporting to this list?

Would it be wise to write to the debian-user list and ask there if anyone 
encountered this problem as well? 

Kind regards,
Jonathan
