Hopefully :-)
There may be a possibility, however, that bugs in PHP could cause
corruption of the shared memory cache that would ultimately lead to
failure. This might not be a problem that would show up otherwise because
PHP frees its memory and recreates compiled code each time. This is
precisely what phpa doesn't do, hence the acceleration. So if memory was
being corrupted because of a php bug, the mangled memory would be there to
be used in subsequent requests, and might cause them to fail, whereas for
php without phpa, the memory might be corrupted but not matter because the
memory is going to be freed anyway.
The bottom line is that you should try php/phpa and see what happens. If
there are problems then they'd probably make themselves evident within a
day or so. If, as is generally the case, there are no problems, then great.
If there are issues then just let me know.
