[Zope] Server not found or DNS error

[Alexander Chelnokov]

Hello All,

A problem appeared recently after some system reconfiguration (now
Debian 3.0, Zope 2.6.2, Postgresql 7.2.1 at Celeron-366/512 Mb RAM,
Apache is not used)- opening any link in a Zope application (mostly in
OIO, www.txoutcome.org) unpredictable causes "Server not found..."
error and if through Squid - "Zero sized reply" or "Permission
denied".  Pressing "Refresh" 4-10-12 times still opens the link. Any
hint how to fix this?
