I have moved my plone 2.5.5 site from one hosting environment to another. I did this by simply migrating the VMWare VM from one machine to another in a different hosting environment, then switched DNS over.
The site has been running fairly happily for a few years in the old setup, and runs much faster in the new.
However, one of the two sites seems to hust 'hang' now, while the other (same instance) is running perfectly. No changes at plone/zope level, no changes to Apache. It's a fairly simple set up with Apache, a single zeo and cachefu as standard. Server is fedora 5.
Can anyone please help with some tips to debug this... or even to explain why this might happen?
Everything else is working fine on the server. I have checked for hung python threads using instructions on
http://plone.org/documentation/how-to/use-gdb-to-get-backtraces-of-hung-spinning-sites but there is nothing.
Regards,
Barry
