FATAL ERROR IN TWO-TASK SERVER: error = 12571

Hello,

we have ODAC 5.70.0.30 in the NET option.
Clients work over terminal clients and have
from time to time very nusty problem with locked (not deadlocked!) table.
We see that lock is related to execution of delete on a table with primary key that is executed withing PL SQL package. It looks like delete was executed and commit was not, that result in a lock of the table (table with primary key).
Timely correlated there is a trc file with following error:
FATAL ERROR IN TWO-TASK SERVER: error = 12571

Any ideas are highly appreciated.

Vladimir.

Probably, this error is not related to ODAC. Try to debug your application and PL/SQL packages to find out when this error occurs.
