[HTCondor-users] condor_collector crash every 15min, ERROR "Assertion ERROR on (ip_string)"

["Ke, Hongwei" <kehw@xxxxxxx>]

Hello,

We have recently setup a condor cluster with a few machines in a isolated network, which has no internet access. IP addresses are assigned by the interface configuration file and hosts can be resolved by hosts file. Everything works very well almost out of the box, but the condor_collector crashes every 15min with the following messages. Has anyone seen this before? Thank you very much!
