[ZODB-Dev] Unexpected ClientDisconnected Behaviour

[Chris Withers]

Hi, got a question relating to the log at the end of this mail...

returned to work on a project this morning, I'm developing on a Windows ZEO 
client attached to a Debian storage server, been working great :-)

Except, I guess the ZEO connection got dropped over night. Fair enough, I guess, 
it hadn't had any data down it for a day or two...

BUT, on viewing the ZMI, the first thing I got was a ClientDisconnected error 
shown in the standard_error_message.

That seems bad to me:

1. The next refresh did was fine, the connection just re-established itself.

2. Given 1, why should the end user see the error at all? Shouldn't ZEO attempt 
to reconenct before raising an exception that's likely to get propogated to the 
end user?

cheers,

Chris

PS: here's the event log if it's useful:
