[... good description elided...]
Thanks for a comprehensive description of the problem.
It *may* be an application or environment issue, especially as both app servers
fail at nearly the same time. Common mode failures such as this could indicate:
- Shortage of memory on the server causing OutOfMemoryException, after which
anything could happen!
- If your application uses other resources (such as a database), is the
database doing anything unusual at around these times? Suddenly long response
times, down for maintenance, or similar?
- If the app is an Internet application, is one of the web crawlers suddenly
hitting it with a massive load and saturating it?
- Is the virtual machine being starved of resources at these times due to
something else happening on the host?
All just vague ideas at this point, and I suspect you have already considered
and rejected them!
