FAQ: error 1205

I am getting an error 1205 - what can I do?

Answer:

Error 1205 is a deadlock error.
It is the full error 1205 message text:

Your transaction (process ID #%d) was deadlocked with another process
and has been chosen as the deadlock victim. Rerun your transaction.

Your application should intercept the error 1205 and respond by resubmitting the transaction.
