[Serusers] Error Message

A bit confused by startup message:

0(16102) ERROR: shm_mem_init: could not attach shared memory segment: No space left on device 0(16102) could not initialize shared memory pool, exiting... Too much shared memory demanded: 33554432

I found prior message to upgrade Kernel to 2.4 - currently I'm on 2.6.8-022stab076.1-enterprise At another place it said to recompile ser with SYSV shm instead of mmap (remove -DSHM_MMAP from Makefile.defs) <= This I'm not sure exactly how / what to change in Makefile.def. And yet another regarding no PTR <= I've contracted ISP regarding this, but was hoping to bypass - I was hoping there was some temporary fix for this until they act?

I'm running SER 0.9.6

Thanks for any assistance.
