After enabling POOL started getting this message "Argument out of range" eventually, there any relation?

More information, some sessions are configured to "AutoCommit = True", this problem occurs when destroying the connection, return to the POOL.

When exactly do you get this error message?

This occurs when the component is released "OracleSession.free" eventually, log exception:

[Linked Image]

Exception:
Type: EArgumentOutOfRangeException
Message: Argument out of range.

My connection pool:

OracleSessionPool := TOracleSessionPool.Create(nil);
with OracleSessionPool do begin
Homogeneous := True;
Max := 300;
Min := 10;
PoolType := ptDefault;
TimeOut := 30;
end;

My session:

FConnection := TOracleSession.Create(nil);
with FConnection do begin
Pool := OracleSessionPool;
Cursor := crDefault;
AutoCommit := True;
RollbackOnDisconnect := True;
end;
