Hi,
during log playback I ran into this error which started being written out in an (endless?) loop in the terminal:
Error [Param.cc:181] Unable to set value [-nan -nan -nan -nan -nan -nan] for key[velocity]
Also since Gazebo 5 I get multiple of these when I start gazebo:
Error [Param.cc:181] Unable to set value [0,100000001] for key[near]
Error [Param.cc:181] Unable to set value [0,899999976] for key[constant]
Error [Param.cc:181] Unable to set value [0,00999999978] for key[linear]
Error [Param.cc:181] Unable to set value [0,00100000005] for key[quadratic]
This issue has been around for a while, see question, however only resolved with a quick workaround fix.
Cheers, Andrei
