I get the following error sometimes..

May 4 11:53:35 dns2 ser[28473]: ERROR: append_branch: max nr of branches exceeded
May 4 11:53:35 dns2 ser[28473]: lookup(): Error while appending a branch

I read it was because the destination set has to be increased. I have to check configur.h file but where is it? I can't find it. I only found in ser.cfg childre=4
