How to increase the execution time and/or memory allowed for "orange bar" reloads

If you have a very large dialplan, such that the file /etc/asterisk/extensions_additional.conf starts growing to be more than a few hundred K in size, you may find that not enough time and/or memory is being allocated to permit an "orange bar" reload to proceed. If that's the case, you may need to edit /etc/php.ini. Look for the section headed:

;;;;;;;;;;;;;;;;;;;
; Resource Limits ;
;;;;;;;;;;;;;;;;;;;

Directly underneath you will see the values for max_execution_time and memory_limit - try doubling these from their current values (within reason, of course - you can't allocate more memory than you have available!). If that's not enough, increase them a bit more. Now you should be able to process those monster dialplans!
