[jboss-user] [JCA/JBoss] - Re: Validation of destroyed connections

I'm maintaining a pool with 5 connections and validations every minute. On creation, I assign them an id for monitoring. Here you can see a test case I've already done: On startup jboss creates 5 connections (ids 1 to 5), and validates them every minute. In a given moment, the EIS closes all connections, so the validation of all of them fails and jboss destroys them: 18:24:25,314 INFO [TAManagedConnectionFactory:142] VALIDATING CONNECTIONS.... 18:24:25,314 INFO [TAManagedConnection:249] Validating connection 2 18:24:25,314 INFO [TAManagedConnection:290] I/O ERROR 18:24:25,314 INFO [TAManagedConnectionFactory:150] Invalid connection found 18:24:25,314 INFO [TAManagedConnectionFactory:154] VALIDATION FINISHED 18:24:25,314 WARN [JBossManagedConnectionPool:657] 18:24:25,314 INFO [TAManagedConnection:150] Destroying connection... 18:24:25,314 INFO [TAManagedConnection:160] Connection destroyed 18:24:25,314 INFO [TAManagedConnectionFactory:142] VALIDATING CONNECTIONS.... 18:24:25,314 INFO [TAManagedConnection:249] Validating connection 3 18:24:25,314 INFO [TAManagedConnection:290] I/O ERROR 18:24:25,314 INFO [TAManagedConnectionFactory:150] Invalid connection found 18:24:25,314 INFO [TAManagedConnectionFactory:154] VALIDATION FINISHED 18:24:25,314 WARN [JBossManagedConnectionPool:657] 18:24:25,314 INFO [TAManagedConnection:150] Destroying connection... 18:24:25,314 INFO [TAManagedConnection:160] Connection destroyed 18:24:25,314 INFO [TAManagedConnectionFactory:142] VALIDATING CONNECTIONS.... 18:24:25,314 INFO [TAManagedConnection:249] Validating connection 4 18:24:25,314 INFO [TAManagedConnection:290] I/O ERROR 18:24:25,314 INFO [TAManagedConnectionFactory:150] Invalid connection found 18:24:25,314 INFO [TAManagedConnectionFactory:154] VALIDATION FINISHED 18:24:25,314 WARN [JBossManagedConnectionPool:657] 18:24:25,314 INFO [TAManagedConnection:150] Destroying connection... 18:24:25,314 INFO [TAManagedConnection:160] Connection destroyed 18:24:25,314 INFO [TAManagedConnectionFactory:142] VALIDATING CONNECTIONS.... 18:24:25,314 INFO [TAManagedConnection:249] Validating connection 5 18:24:25,314 INFO [TAManagedConnection:290] I/O ERROR 18:24:25,314 INFO [TAManagedConnectionFactory:150] Invalid connection found 18:24:25,314 INFO [TAManagedConnectionFactory:154] VALIDATION FINISHED 18:24:25,314 WARN [JBossManagedConnectionPool:657] 18:24:25,314 INFO [TAManagedConnection:150] Destroying connection... 18:24:25,314 INFO [TAManagedConnection:160] Connection destroyed 18:24:25,314 INFO [TAManagedConnectionFactory:142] VALIDATING CONNECTIONS.... 18:24:25,314 INFO [TAManagedConnection:249] Validating connection 1 18:24:25,329 INFO [TAManagedConnection:290] I/O ERROR 18:24:25,329 INFO [TAManagedConnectionFactory:150] Invalid connection found 18:24:25,329 INFO [TAManagedConnectionFactory:154] VALIDATION FINISHED 18:24:25,329 WARN [JBossManagedConnectionPool:657] 18:24:25,329 INFO [TAManagedConnection:150] Destroying connection... 18:24:25,329 INFO [TAManagedConnection:160] Connection destroyed Inmediately jboss creates 5 new connections (ids 6 to 10) in order to fill the pool: 18:24:25,329 INFO [TAManagedConnection:111] Initiating connection... 18:24:25,329 INFO [TAManagedConnection:118] Connection established 18:24:25,329 INFO [TAManagedConnectionFactory:111] Connection created -
