Your application is creating cross-database references. The version of  
ZODB you're using on the ZEO server doesn't support packing databases  
with cross References. Upgrade your ZEO server to ZODB 3.8.1 or ZODB  
3.9.

Cross-database references are presumably created if something in the  
session references a persistent item from the main ZODB, or vice  
versa.  Those references would then get broken if Zope restarts  
(clearing the session from RAM) or if one of the databases is packed  
(since the ZODB doesn't support multi-database garbage collection, at  
least not until the separate package Jim made recently for that  
purpose).

You'll have to figure out where in GetPaid these references are  
getting created, and stop doing that.

Thanks,

  I am talking to getpaid developers to see how to fix this, if it is not written in the proper way.
  But the good news is that upgrading to zodb 3.8.1 allowed me to pack again :). I hope I get no side-effects from this...

thanks

I believe ZODB 3.8.1 is used fairly widely with Plone 3 as it is the  
first ZODB that supports blobs. So I think it is fairly safe.
