Stephan, This likely means that the interbase database adapter essentially serializes access to the database. You may want to try sending a mail to the DA maintainer if he is not on the list... Thanks! - C ----- Original Message ----- From: "Stephan Herschel" <stephan.herschel@proceryon.at> To: <zope-dev@zope.org> Sent: Tuesday, December 11, 2001 9:30 AM Subject: [Zope-dev] more than one user: zope 'hangs'

Hello,

We have got a funny problem in Zope: if user A issues a long-running query user B also has to wait in the meantime - zope just waits for A's query to finish.

We are using interbase as our database and GV Interbase Database Adapter 0.9.6 on a linux system. In the README it says 'threadsafety ... is set to 1 - threads may share the module but not connections'

Somehow i suspect the problem lies there. Can anyone give me a hint on this problem?

Thanks in advance, Stephan
