CVS update fails with "Broken pipe"

[Klaus Zeitler]

For the last few feeks I have a strange problem.
When I try to update my CVS emacs version with "cvs update"
nothing happens for approximately 8 min and then I get the following error:
cvs [checkout aborted]: error writing to server: Broken pipe

The first anonymous CVS checkout with
"cvs -z3 -d:pserver:address@hidden:/sources/emacs co"
works just fine. From then on, an update (or checkout again) command
fails like mentioned above.

Here's an example:
$ cvs -t update
  -> main: Session ID is wFsBDcMzUa1LMxYs
  -> main loop with CVSROOT=/sources/emacs
  -> open_connection_to_server (:pserver:address@hidden:/sources/emacs)
  -> Connecting to cvs.savannah.gnu.org(199.232.41.69):2401.
  -> rename(CVS/Entries.Backup,CVS/Entries)
  -> unlink_file(CVS/Entries.Log)
  -> rename(CVS/Entries.Backup,CVS/Entries)
  -> unlink_file(CVS/Entries.Log)
  -> rename(CVS/Entries.Backup,CVS/Entries)
  -> unlink_file(CVS/Entries.Log)
  -> rename(CVS/Entries.Backup,CVS/Entries)
  -> unlink_file(CVS/Entries.Log)
  -> rename(CVS/Entries.Backup,CVS/Entries)
  -> unlink_file(CVS/Entries.Log)

And after approx 8 minutes I get:
cvs [update aborted]: error writing to server: Broken pipe

I had used this command for more than 2 years without any problems
and I haven't changed anything in my environment (not that I can think
of at least).
When I remove my emacs directory and try the checkout command,
it works just fine. But when I now follow up with an update or
a 2nd checkout command, I get the same 'Broken pipe' error.

OS: SunOS 5.8 Generic_117350-28 sun4u
sparc SUNW,Sun-Blade-1500 Solaris

Does anybody have an idea how I can investigate this?
I appreciate any help. Thank you

Klaus
