Assigned to me.  Turns out Jeremy fixed this in ZODB 3.3 long ago (part of ZEO is abusing asyncore's socket_map in a way that "didn't matter" before).

His checkin comment noted that the relevant change to Python's asyncore will also show up in Python 2.3.5 (if that's ever released).  If so, the same failures will occur with 2.3.5.

On Windows the error msg is a bit different:

select.error: (10038, 'An operation was attempted on something that is not a socket')

Looks like these come out of two related tests:

   testNOK (ZEO.tests.testAuth.PlainTextAuth)
   testNOK (ZEO.tests.testAuth.DigestAuth)

Curiously, the same tests pass on Zope 2.8 trunk under 2.4, and in Zope3 under 2.4.

Unfortunately, I have no idea what those tests do.  Possibly relevant is that 2.4's asyncore is less tolerant of leaving garbage in its socket_map (like closed sockets).

Zope 2.7.3 + Python 2.4 fails when running the unittests:
