I'm getting an access fault during iocInit when I load
iocAdminVxWorks.db from devIocStats:

My vme is using VxWorks 6.8, base-3.14.12.2, and devIocStats-3-1-7 (from
synApps_5_6).  The problem also occurs with devIocStats 3.1.9.

I've used the debugger to trace the fault to the iocInit.c:doRecordPini
for the record iockmp:DAT_MBUF_MAX.

The problem doesn't occur with VxWorks 5.5.2.
