Re: [HTCondor-users] HTcondor High-Availability and dual-stack

[Carles Acosta <cacosta@xxxxxx>]

Hello again,

I've updated my pool to version 8.5.5 and, using ENABLE_IPV4=auto, 
ENABLE_IPV6=auto and PREFER_IPV4=true options, the error is gone. 
However, when I change to PREFER_IPV4=false, there is still this error 
related with HA daemon:

HAD CONFIGURATION ERROR:  my address 
'<ipv4:51450?addrs=[ipv6]-51450+ipv4-51450>'is not present in HAD_LIST 
'xxxx.pic.es:51450, xxxx.pic.es:51450'

Cheers,

Carles
