[Skimmertalk] skimmer server crash?

[N4ZR]

Skimsrv has a few chronic issues.  In addition to what Dave is 
reporting, my Skimsrv occasionally crashes right after startup, with an 
error message about trying to write to "address 0000014".  After that, 
when re-started right away it runs for days with no issues. Once or 
twice I've seen run-time errors involving writing to other, apparently 
spurious addresses.
