Hi,<br>I've been using the ZODB pretty intensively for a few weeks now, and suddenly have started getting intermittent Database conflict errors, after which calling conn.sync() makes no difference, and I cannot get back to the pre-exception state in one of my ZEO clients, although all the others continue quite happily.<br>
<br>I was using 3.7.0a0 and downloaded the 3.8 egg. The behaviour remains the same.<br><br>I am using a ZEO server with filestorage, and have tried rebuilding the database from scratch, but the intermitent conflict error appears.<br>
<br>The error is :<br> database conflict error (oid 0x029b, class btreelist.BTreeQueue, serial this txn started with 0x03750b64c9cf1f00 2008-04-11 08:36:47.299000, serial currently committed 0x03750b64ca57a788 2008-04-11 08:36:47.424000)<br>
<br>BTreeQueue is a very simple wrapper over IOBTree. Using integer keys. <br><br>Question : What does the "conflict error" actually mean ?<br>Question : All my other ZEO clients continue happily -- and even this process works ***most*** of the time. Short of dropping the ZEO connection and rejoining is there a way of resetting the ZEO session?<br>
