Your PHP script has bug that consume all your memory, probably an infinity loop.

It will use it up no matter how high the memory limit you set.

You need to locate and fix the bad PHP code.

disable EacceLerator
will save some (maybe a lot) memory.

anyway you can try disable it, see if any improvement during high traffic

i disabled all
LiteSpeed Enterprise 4.2.12 ,LSAPI 6.6
PHP5.3.27 EacceLerator V0.9.6.1-ea
ionCube V4.6.1
Zend Guard Loader v3.3
Suhosin V0.9.33
then out of memory.
when Suhosin V0.9.33 enabled 503 happened.
if there are few visitors（3~5 process）. single php process take memory 40mb~70mb
but when more visitors，single php process take hard memory from 40mb grown over 7gb，but not all，some occupy hard memory normal.

this is terrible -- already allocated 8G memory
so please refer #2 reply.
you have to improve the php code, for example if it's wordpress site, disable plugin one by one, maybe one plugin has caused the memory nightmare.
