Hi,

if you look at the TODO file, you will find that the
pathmanagement block has an error right there, and I have now started
to look closer at this.

Indeed in the functions pm_enableHB() and pm_setPaths()
these values get set...I have made a fix for the problem mentioned
in the TODO file. I suspect that the statement :
if(hearbeatIntervall >= RTO_MIN && hearbeatIntervall <= RTO_MAX)
in pm_enableHB() is the cause of your problem. If you just
replace the RTO_MIN by the value you want and recompile, you
should be set.

Since I did not write the pathmanagement block, I am not
all too sure about the draft - I will have to read it again. And
then look at the code again :-)
Anyway, if you have these requirements, and you have suggestions
how to change the program, I will be happy to do so, if you send a
reasonable patch.
