HY000 -1 Error

[Mark Jutras]

I'm currently trying to update a file in our Legacy
system with the use of JDBC. I have a loop that
successfully updates up to only 223 records and then errors
out with the message:
Unable to open DRA0:[IN.FILE.01]INVENTORY.DAT.
Unable to send message to server.HY000 -1.
I believe I'm using the sun.jdbc bridge driver for this, version 2. Any reason why this is happening would be
greatly appreciated.
Thanx in advance,
Mark
