These indicate that phpa has detected that php has crashed. Have you also
upgraded PHP, or just phpa? When you upgraded, did you also remove all
phpa_* cache files? (you should do this) Which version of PHP are you
using? 4.1.2 is known to cause segfaults for some people even without phpa
installed. Try running without phpa for a while, e.g. a day. Do you get any
segfaults in that time?

As I've commented in the forum, these warnings aren't really a problem. The
message is meant to indicate a problem, and is something that I added in
this release, but I later realised that they can also occur for a valid
reason, and I believe that is what's happening. They may be a nuisance but
you should ignore them. I'll try and do something about them in the next
release, either by taking them out, or eliminating the case that is most
likely causing them now.
