[Zope] ZODB/FSSession TransactionError

[Brian McClain]

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

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:

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,
