Several times lately, we've seen our development Zope server (running CVS of a few days ago) go into a mode where all requests return back this: Error Type: TransactionError Error Value: 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. The only thing in the log is this: 1999-11-24T05:51:23 PANIC(300) ZODB An storage error occurred in the last phase of a two-phase commit. This shouldn't happen. The application may be in a hosed state, so we will not allow transactions to commit from here on How can I debug this further??? Help? Anthony
