After playing around successfully with FSSession for a while, I ran into the following error when calling FSSession: 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. Traceback (innermost last): File /usr/local/dc2/Zope-2.1.0-linux2-x86/lib/python/ZPublisher/Publish.py, line 214, in publish_module File /usr/local/dc2/Zope-2.1.0-linux2-x86/lib/python/ZPublisher/Publish.py, line 179, in publish File /usr/local/dc2/Zope-2.1.0-linux2-x86/lib/python/Zope/__init__.py, line 202, in zpublisher_exception_hook (Object: short9_panic2) File /usr/local/dc2/Zope-2.1.0-linux2-x86/lib/python/ZPublisher/Publish.py, line 169, in publish File /usr/local/dc2/Zope-2.1.0-linux2-x86/lib/python/ZODB/Transaction.py, line 209, in commit TransactionError: (see above) And from the log file: 2000-06-27T16:33:19 PANIC(300) ZODB A 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 I also get the following error on occassion when calling FSSession: Error Type: EOFError Error Value: Traceback (innermost last): File /usr/local/dc/Zope-2.1.0-linux2-x86/lib/python/ZPublisher/Publish.py, line 214, in publish_module File /usr/local/dc/Zope-2.1.0-linux2-x86/lib/python/ZPublisher/Publish.py, line 179, in publish File /usr/local/dc/Zope-2.1.0-linux2-x86/lib/python/Zope/__init__.py, line 202, in zpublisher_exception_hook (Object: ApplicationDefaultPermissions) File /usr/local/dc/Zope-2.1.0-linux2-x86/lib/python/ZPublisher/Publish.py, line 165, in publish File /usr/local/dc/Zope-2.1.0-linux2-x86/lib/python/ZPublisher/mapply.py, line 160, in mapply (Object: short9_panic2) File /usr/local/dc/Zope-2.1.0-linux2-x86/lib/python/ZPublisher/Publish.py, line 102, in call_object (Object: short9_panic2) File /usr/local/dc/Zope-2.1.0-linux2-x86/lib/python/OFS/DTMLDocument.py, line 166, in __call__ (Object: short9_panic2) File /usr/local/dc/Zope-2.1.0-linux2-x86/lib/python/DocumentTemplate/DT_String.py, line 502, in __call__ (Object: short9_panic2) File /usr/local/dc/Zope-2.1.0-linux2-x86/lib/python/Products/FSSession/FSSession.py, line 116, in __call__ (Object: FSSession) File /usr/local/dc/Zope-2.1.0-linux2-x86/lib/python/Products/FSSession/FSSession.py, line 142, in load (Object: FSSession) EOFError: (see above) I have plenty of disk space and have tried reinstalling FSSession/Zope, rebooting, etc... I am running Zope 2.1.0 and FSSession 0.3.1 Any advice would be greatly appreciated, Brian McClain
