I was not speaking of the sandbox, but the repository itself. However,
if a different sandbox did not have the problem, then it seems likely
that your CVS/Entries file was somehow corrupted.

That would be a matter of looking in bug tracking for your vendor
(Redhat for version 7.1) to see if there were any bug reports against
the kernel you are using.

The line in entries.c is this one:
    if (fprintf (fp, "/%s/%s/%s", p->user, p->version, p->timestamp) < 0)
so it miht be interesting for you to issue the commands

  up
  up
  p *p

in order to see if it was p->user or p->version or p->timestamp that was
giving fprintf() the problems.
