I have UDB DB2 ESE 8.1 whit FixPack 2, where they are had 3 databases.
I have a table federated in one database.
after a time no longer I can make consultations to this table federated.
simply the consultation remains in infinite delay, without having no answer.
also no other application can make consultations to the others databases. single if I do restart to the machine, everything returns to its normality. until it returns to block itself.

single the file db2diag.log, makes reference to the following error
