My current hosts are great but failing to come up with an answer as to why I am suddenly getting, after several years with C5.6, getting random & repeated logouts (sometimes a few seconds apart) across several sites. Coinciding with this are less frequent error msg (related to it?) that I have appended below.

Happening on different Browsers and on different computers. Don't understand sessions etc. Where do I start investigating what might be wrong. Been going on for a week.
