Hi, I once in the while get the following warning in my Zope 3 log, which I'd like to resolve:
2009-10-07T14:35:41 WARNING ZopePublication Competing writes/reads at /BSPSite/act/++vh++http:zis.act.at:80/bankneu/++/c/acc/booklist/index.htm l: database conflict error (oid 0x7a5d, class BTrees.OOBTree.OOBTree, serial this txn started with 0x0381388ca6804966 2009-10-07 12:28:39.023700, serial currently committed 0x03813893b087d0cc 2009-10-07 12:35:41.374343)
That URL looks like it should only be reading the database, but the fact that you get a conflict error suggests that the code behind that URL is writing to the database. If I were you, I would first ensure that read operations never write to the database.
That's exactly the problem - it's a read operation and there should not be any write operation involved. However, it's hard to find out where the write operation in my code occurs, I can't find it in the view, maybe there's something in the authentication code, but I'd have to dig deep through my source. So It would be extremely helpful to know a faster way to find out what code triggered this warning.
