Hi,

I have a transaction that updates several tables und runs a few minutes.
During this transaction, another connection makes SELECTs from tables
that are being modified by the first connection. Althaugh the second
connection doesn't modify any rows, it has to wait until the first
transaction is commited.
I didn't specify a concurrency mode and the first transaction didn't
explicitly lock any rows or tables for update.

Do you have an idea what might be wrong here?

Greetings
Tim
