High fragmentation usually means memory allocated is not enough. Try increase apc.shm_size 384M or bigger.

increase memory limit in LSPHP5 External App in Admin Console (Configuration => Server => External App). likely it is not enough to hold allocation for APC.

Which variable exactly can you point out?

That value has to be the same for apc.shm_size also?

If you enable PM i can send you the apc stats URL.
