Interesting. Could you send me a copy of your bb-hosts file so I can see
how your dns checks are configured ?


Thanks,

I had same problem as Lars (under Solaris 9)
I removed following entries with dns tests from bb-hosts and it doesn't crash anymore:

130.223.8.20   uldns1     # dhcp dns smtp ldap://uldns1/o=universite%20de%20lausanne,c=ch
130.223.4.5    uldns2     # dhcp dns smtp ldap://uldns2/o=universite%20de%20lausanne,c=ch

I think this should fix it - goes on top of todays snapshot.
