There are several reasons for the TNS-12518 errors, however this problem

usually can related to insufficient allocaction of memory resources.

This issue is described further in Metalink note 371983.1

Additionaly you can see if some error was reported on Windows Event

Viewer near the time when the incident happened.

Also, check oracle listener.log as it will contain more information.

You can to connect using Oracle sqlplus / as sysdba and check the

resources using the command :

select * from v$resource_limit;

and observe the amount of sessions/processes. Compare this to the

value of sessions/processes you have set, possibly it is too low.
