checksum failure on heavily loaded client and large files

[Peter Toft]

I have problems with CVS - start reading the thread
http://lists.gnu.org/archive/html/info-cvs/2006-06/msg00005.html
and there was a second round at
http://lists.gnu.org/archive/html/info-cvs/2006-06/msg00103.html

What I see is 
* for a CVS client (CVS 1.12.9 or 1.12.13), 
* a server with same CVS version
* submitting over a somewhat slow network using SSH as bearer (SSH 3.6), 
* where I have a single CPU Linux Red Hat AW 3 client - heavy CPU load!!
* the server is a 16 CPU Linux Red Hat AS 3
* our XML files are of this order for version 1.12
  wc test.xml,v
    245334  388016 2144072 test.xml,v
  wc test.xml.mdb
     59377   67126  431144 test.xml
* Roughly it is so that a new version of "test,xml" creates 
  fundamentally new content of the file i.e. diff would show
  almost all (if not all) lines are changed. 
* The CVS server and client are in different time zones - but both should 
  be NTP synched.

In this case I see from time to time that a cvs update gives

P test.xml
cvs update: checksum failure after patch to ./test.xml; will refetch
cvs client: refetching unpatchable files
cvs update: warning: `test.xml' was lost

I am getting more worried about this....
All help is highly appreciated!

Best
