Glassfish e restart do Firebird

Front-end
#1

Boa tarde
Estou trabalhando com uma aplicação Java Web com glassfish e banco de dados Firebird. Quando eu reestarto o serviço do Firebird a aplicação para de se conectar ao banco e dá o seguinte erro:

Caused by: org.firebirdsql.jdbc.FBSQLException: GDS Exception. 335544721. Unable to complete network request to host ""., error code: HY000

Alguém sabe porque o glassfish não se reconecta ao banco automaticamente?
