Public bug reported: There is a conflict between these 2 packages options that can cause network trouble with ease. iputils-arping use the option "-w" for timeout in second whereas arping use the same option for timeout in microseconds.
Installing a pgpool2 cluster (for example) from Ubuntu universe repository use by default the arping cmd for the gratuitous ARP Virtual IP. arping_cmd = 'arping -U $_IP_$ -w 1' Using by default the arping package instead of iputils-arping can cause serious trouble to you network (tremendous layer2 broadcast). A quick fix could be switching the -W (second) and -w flag (microsecond) on arping package. Seems to be a good idea to harmonize the flags for those 2 similar packages.
