Second Call:
Error Type: TransactionErrorError 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.
