Hello Mr. Haqa. I think i found a bug in your ZStyleSheet Product. For some strange reason, after upgrading to the version 4.2.3 of it in sync with Zope 2.5.1b1, my ZODB started to get bigger and bigger with no apparent reason. So, i asked on the #zope irc channel and SteveA told me to use tranalyzer.py to see what was bloating it. So, after running tranalyzer, i found a lot of lines like this: TID: 3438E1065A63CCC @ 139644468 obs 86 len 22979 By Anonymous User "/ucs/tplPadrao/estilos.css/index_html" OID: 214ad len 221 [Products.ZStyleSheet.ZSSAttribute.ZSSAttr] OID: 214ae len 221 [Products.ZStyleSheet.ZSSAttribute.ZSSAttr] OID: 214ac len 225 [Products.ZStyleSheet.ZSSAttribute.ZSSAttr] OID: 21481 len 221 [Products.ZStyleSheet.ZSSAttribute.ZSSAttr] So, the only thing that i can realize about this, is that the ZStyleSheet is writing something to the ZODB with each access my home page. I did not tried to look at the source to figure what the problem is, but i will do it soon while you fix this. Thank you for your great product.
