Usually, the dates are reliable -- unless your system has severe
memory problems...

Startup problems (these are those where nothing appears in the
event log file) are best analysed via:

      export EVENT_LOG_FILE=<logfile name>
      bin/runzope

You should see all log messages in the file identified
by "<logfile name>" -- even those that are usually
suppressed (for an arcane feature).

There is a HowTo about "Debugging a spinning Zope".
It may help you to analyse the problem.


However, from your description, I would not trust your server.
Maybe, there is some hardware problem.

We, too, run busy Zope sites and have not seen any of your problems.
