Hi Ken, I queried them about the Apache kills and they returned saying this (see below). I'm about to start testing it again and see if it resolves the issues I'm having.
"Thank you for contacting our Help Desk.
The logs you provided us with are generated from Apache itself.
According to the errors recorded there I have added the following lines in your .htaccess in order for Apache timeout to be extended dynamically.
<Files ~ ".php">
SetEnvIf Request_URI "index" DynamicTimeout=300
Please verify the result on your end."
