Some network issues can cause mapupdate to hang during DNS lookup system calls sporadically. This results in a long running mapupdate process which never exits and prevents all future mapupdates until the process is killed
Product Defect 312689:
* vasypd: If DNS occasionally hangs, still properly kill map update process.
Also handle get_domain_reachable.
