can't read "Blackhole_Match"
Hi,
I'm using https://devcentral.f5.com/articles/v111-dns-blackhole-with-irules to blackhole some domains. However, once every few requests I see this error :
Jul 28 18:51:30 err tmm3[10586]: 01220001:3: TCL error: /Common/PROTECT_DNS_BH - can't read "Blackhole_Match": no such variable while executing "if { $Blackhole_Match } { This DNS request was for a Blackhole FQDN. Take different actions based on the request type. switch [DNS::..."
I've went over the external file, seems like everything is in place. Also, the blackhole worked, just this error sometimes.
Can anyone direct me what to check ?
Thanks!
