Strange update behavior

[Christian Schmolzi]

Hi,

I have noticed a strange behavior that occured exactly two times in the 
last few weeks. I tried to update my sandbox (Sun Solaris, CVS client 1.12) 
from a branch to HEAD with "cvs -PAd". Strangely, one file, that was added 
since that branch was not retrieved from the repository (CVS Server 1.12 on 
Linux, pserver). Since the cvs server simply ignored that file, we did not 
notice at first that the file was missing.

Several update tries with differnt options did not succeed. The only way to 
get the file from the repository was by telling cvs explicitely which file 
to update ("cvs update -P file.txt"). Another colleague of me reported this 
behavoir happened with his windows client (WinCvs).

Does anybody know under which circumstances something like this can happen. 
Since that I have not been able to reproduce this behavior but we are a 
little concerned about the reliability of a cvs update before we deliver 
our software to the customer.

Thanks,
Chris
