Hi,
I have a Apache 2.0 and a ZServer w/ VHM behind it. The Apache uses
RewriteRules to serve the ZServer content. The problem is every so
often, the zope server stops responding with a
*Proxy Error *
The proxy server received an invalid response from an upstream server.
The proxy server could not handle the request /GET / </>/.
Reason: *Error reading from remote server*
Apache/2.0.43 Server at nbs.neuro-bs.com Port 80/
/
and my zope debug log has:
2003-03-10T19:09:03 INFO(0) Z2 Caught signal SIGTERM

The zope process seems to be still there, but only a restart fixes the
problem.
Any ideas as to what is going wrong??
Thanks.
