Hi,

 

 

Here is an excerpt of the code form the LB_FAILED event

 

 

set pool [LB::server pool]

 

set act_nodes [active_members $pool]

 

 

With the PVA turned off $pool contains the name the pool that failed and of act_nodes contains the number of active nodes (0). If I turn on the PVA and retry the request pool contains "" and I get a TCL runtime error setting act_nodes (which I expect when pool is ""). I turn off the PVA and retry the request and it $pool contains the name of the pool that failed.

 

 

 

Regards,
