[Zope] ZEO ClientDisconnected error

Hi there,
One of my clients is using Plone on Solaris 9. We have set up one ZEO
client on a Solaris machine and a ZEO server on another Solaris machine
(for testing purposes only at this stage).
Performance is great but every morning, the first hit to the Plone site
returns a ClientDisconnected error (see full error log below). It looks
like the socket on the server gets corrupted or something.
When the error occurs, the server is non-responsive for a while
(anywhere between 10 sec and 2 minutes) and then eventually the server
responds.
Has anybody seen that before? Is it Zope related or should I look in
other directions?
Researching Zope on Solaris, I read somewhere (can't remember where now)
that Solaris doesn't like long-running processes too much (well, the
Zope process, for instance). Could it be the culprit here?
Any advise or pointer welcome.
Cyrille
(in the logs below, "appserv05" is the ZEO client, "pehi" is the ZEO server)
