Hi, some times my zope 2.2.4 server gives the following error: -------------------------------------------------------------------------------------------- Zope Error Zope has encountered an error while publishing this resource. TransactionError Sorry, a Zope error occurred. Traceback (innermost last): File /usr/local/opt/Zope/server/test2/lib/python/ZPublisher/Publish.py, line 222, in publish_module File /usr/local/opt/Zope/server/test2/lib/python/ZPublisher/Publish.py, line 187, in publish File /usr/local/opt/Zope/server/test2/lib/python/Zope/__init__.py, line 221, in zpublisher_exception_hook (Object: Traversable) File /usr/local/opt/Zope/server/test2/lib/python/ZPublisher/Publish.py, line 175, in publish File /usr/local/opt/Zope/server/test2/lib/python/Zope/__init__.py, line 235, in commit File /usr/local/opt/Zope/server/test2/lib/python/ZODB/Transaction.py, line 208, in commit TransactionError: A serious error, which was probably a system error, occurred in a previous database transaction. This application may be in an invalid state and must be restarted before database updates can be allowed. Beware though that if the error was due to a serious system problem, such as a disk full condition, then the application may not come up until you deal with the system problem. See your application log for information on the error that lead to this problem. --------------------------------------------------------------------------------------------- In the documentation I found: --------------------------------------------------------------------------------------------- ZODB.Exceptions.StorageTransactionError Documentation This exception is raised if a storage method is called in an invalid state. Storages are required to raise this error under certain conditions. Applications should never encounter this exception unless there is a bug in ZODB or in a storage implementation. Concurrency sequential Persistence ----------------------------------------------------------------------------------------------- So it look´s like a serious error deep down in the ZODB transaction system. There are no problems on the OS (Linux 2.2.14), no disk full ... The error appears 2 times a week on a live running system with 100000 requests a day. When the error appears the only way to fix it, is to restart the server. Does anybody know the reason for this error? Is there a fix for it?? Is it fixed in Zope 2.3.x ?? Does DC know the problem, do they fix it? Any help is really appreciated. regards Harald _____________________________________________________________________ FRIATEC Aktiengesellschaft Informationssysteme und Organisation Tel. 0621 - 486 - 1454 Fax. 0621 - 486 - 1840 Steinzeugstrasse 50 mailto:harald.koschinski@friatec.de D-68229 Mannheim
