PeterZ <[EMAIL PROTECTED]> reported today very similar problems
in "[EMAIL PROTECTED]". He, too, gets:

Maybe, you have something in common (the same software version, hardware
part) which causes these problems?

Apart from that, I have seen 2 reasons for ZEO lockups:

  *  a firewall between the ZEO clients and the ZEO server
     which dropped connections without informing the connection

  *  ZEO clients that access the same storage (in the same ZEO)
     via two different connections (leads to a commit deadlock).
