You're not using a 64 bit version. Is there a 9.40.FCn version
available?

Thanks,

Subject: How can I use 32Gb of ram in IDS 9.4 [20124]

I have IDS9.4 on Suze 8.2 on a IBM 445 with 8 CPU and 32 Gb of ram

How Can I use more of the Ram ?

I have tried playing around with buffers but if I go past 280000 the
instance
dosn't come on like and complains :

Segment locked: addr=0x44000000, size=1450098688
shmat: [ENOMEM][12]: out of available data space, check system memory
parameters (e.g. MAXMEM)

My onconfig is :
