If find-activate.pl gets an ICMP udp port 53 unreachable message when trying to resolve the root nameserver, it keeps re-trying in what seems an infinite loop.
This might eventually result in an out-of-memory condition.
If find-activate.pl gets an ICMP udp port 53 unreachable message when trying to resolve the root nameserver.
This must be done per unit (each VIPRION blade, all BIG-IP systems in an HA configuration, etc.). Perform the following steps as the root user: 1) mount /usr read-write (see SOL 11302) mount -o remount,rw /usr 2) edit the file: /usr/lib/perl5/Net/DNS/Resolve/Recurse.pm line 115 has this statement: return $self->hints(); modify that statement to this: return; 3) sync the filesystems and remount /usr as read-only (remount command, see SOL11302): sync && mount -o remount,ro /usr
find-activate.pl no longer becomes stuck in an apparent infinite loop when unable to resolve root nameserver.
