    Appreciate the pointer Jon !!  Searching on  "Perl signals problems"
yielded a number of hits and the information at this link seems most

The server is currently set in low traffic mode.  Based on my symptoms as I've
described and from what I read at that above link in particular and other
links referencing MaxServers 0  I think my first test is to change to RPC and
set MaxServers 0.  Does that sound very reasonable in your opinion ?
Since this problem is intermittent additional assurances are very welcome.

Again thanks Jon
