the submodule calc_usage exists 2 times in the plugins-scripts/Classes/IFMIB/Component/InterfaceSubsystem.pm
This causes the second version only to be called, however this version fails with a devision by zero if the switch has a configguration issue at one of the network ports.
This has been corrected at the first version of the sub module.
This working version starts at lin 743
the failing second version starts at line 1315
it seems that both modules ar in a different package space, however the submodule isn't called with a package version so only the last version defined is being used
