Can't help you directly, but there are a few questions that might help
...
1. Upgraded as per instructions -
http://www.openbsd.org/faq/upgrade46.html?
Yes, followed the instructions to the letter. Everything else upgraded
successfully and is working as expected.
If I made a mistake, I duplicated the error on both upgrades. I think
this is unlikely.
2. Upgrade included packages at the end of those instructions?
Yes, upgraded packages too. This seemed to go smoothly. I've since
pkg_delete and pkg_add'ed the obvious suspect packages with no effect.
3. Applied errata patches (don't think they would make a difference
here?)
No, I haven't done that as I haven't built from source. Hadn't planned
on having to rebuild packages for this upgrade. I could build from ports
if this is likely to help....
4. What version of Apache? 1.3 in base, or 2.x from ports?
Apache v1.3 standard install from base. Using package defaults. Not
using ports.
5. MySQL and PHP - from packages or ports? What versions?
PHP v5.2.10 from packages (php5-core, php5-mysql)
mysql-client-5.0.83 from packages.
The two servers are drastically different hardware running completely
different web applications. The affected web-sites also work
intermittently. Some requests succeed. Others cause the segfault.
Unfortunately they are production servers and are now unreliable.
I think I have confirmed this is a php5-mysql problem as the server
seems stable with the php5-mysql package removed. It's a little hard to
tell as most of the sites on the servers make extensive use of MySQL
however there is one that doesn't and I was unable to reproduce the
segfault from this site with the mysql packages removed. Re-added the
mysql package and the segfaults returned.
