PHP 5.3.23 - PHP 5.6.3 - Zend framework 1.12 memory usage increase -
we've been running on php 5.3.23 while , have cron jobs use bit of memory due objects , referencing. crons never exceeded 128m though not 64m.
since upgraded php 5.6.3 of these crons use insane amounts of memory , still die, though have not been changed. 1 of these crons surpasses 2gb of memory
is there known cause issue? or have more information on how debug it?
i've tried - putting in function per loop call, references gone after function, - manual garbage collection - unsetting objects manually - xhprof memory usage
it seems keeps climbing up. makes me feel in zend framework mysqli adapter
maybe due opcache, stores bytecode in shared memory. it's enabled in php 5.6 default. more info here.
