Hallo, has anyone a hint what could trigger this exception? This happens once in a while. No change to the database or the connection dictionary before it happens. Trust that the database is configured correctly and that the connection dictionary is ok as well.

TTADMdaten.java:109 = zwischenList = ec.objectsWithFetchSpecification (fetchSpec);

ec is defined in the class as a new EditingContext();

Deadlock????

Java.lang.IllegalStateException: _obtainOpenChannel -- com.webobjects.eoaccess.EODatabaseContext com.webobjects.eoaccess.EODatabaseContext@b69500: failed to open database channel. Check your connection dictionary, and ensure your database is correctly configured.:
