This got me farther, thanks. (BTW, is there a good source for pf
environment variable info? I couldn't find reference to this guy
anywhere, including pfSharedMem(3pf)).

Now my general arena is not big enough and Performer is not letting
me enlarge it (surely from some other system limit, but I can't find it).

environment (systune info at bottom):

export PFTMPDIR=/usr/local/data2/pftmp (7.5GB free on this fs)
export PFSEMASIZE=500000000
export PFSHAREDSIZE=2000000000
export PFNFYLEVEL=7

execution: (summary: pfInitArenas allocates 1/8 of my request)

(assume "<pid> PF Info/SysErr(6):" in front of these messages)

Why does pfInitArenas back off?

Thanks for any tips ..
