We have a duration test that runs for a long period of time with lots of
database activity. After a while we start getting errors from some of the
connections in the pool. Can someone take look at this exception and
provide any input as to what may be wrong?

I am using the 1.0 release of the driver and 1.5.0.3773 of the server.
Connection is local and the OS is Win2K. I am using FBWrappingDataSource as
the connection pool.

I execute SQL like delete from xxx where fk_yyy=1691 and fk_zzz=1 and get
the following exception:
org.firebirdsql.jdbc.FBSQLException: GDS Exception. cannot update erased
record
at org.firebirdsql.jdbc.FBStatement.executeUpdate(FBStatement.java:153)



Any ideas?




Farther down I start to see errors like the one below. They appear to be
related to the connection pool. At this point in my tests the pool has been
used pretty hard for many hours. Sorry for the bad formatting...
