allmon and allmon2 will cause an issue. if you do not use them you will not
have the problem steve. it can be made to cause a crash every time
when used.

this is why i have taken the remote base node off the allmon2 page's
on dial. and will have to do the same for the acid build also.

i am working with dial to make the migration to new
hardware sooner or later.
