[horde] Horde/Apache instability problems

>This is definitely a bug in PHP then. Upgrade to a newer version.

Thank you for the response! I have upgraded PHP from 4.3.9 to 4.4.2 
compiled from source. Unfortunately, the problems have not gone away. 
PostgreSQL is still logging "unexpected EOF on client connection" 
several times per minute, and on occasion Apache core dumps. Examining 
the core files with gdb gives very similar messages to what is listed 
above.

Do you think i should try upgrading to PHP 5? Or is the problem 
elsewhere? The only other thing i can think to try would be to 
reinstall Apache and PHP, switching from 64-bit to 32-bit in the 
process.

For reference, the first few lines of the new gdb backtrace is pasted 
below. The text of line #0 seems to vary; before it did not.
