apache2 crashed with SIGSEGV in T.312()

Binary package hint: apache2

Seems to have been caused by PDO.

The php code in question is attempting to read from a remote mysql database.

The php application is using the concept of connection pooling so multiple PDO connections may be held open at any one time.
