The PCI table reports the amount of address space allocated, not memory. It
is quite common for this to be more than the memory. Sometimes there
are gaps, sometimes the memory is accessible big endian, and little endian
at different offsets - etc

That cgi doesn't lock memory and surely I don't have so much memory.

Looking for lscpci output I have found that amount of detected
memory on my SVGA Tseng ET6000 is incorrect :
00:0f.0 VGA compatible controller: Tseng Labs Inc ET6000 (rev 30)
(prog-if 00 [V
GA])
Control: I/O+ Mem+ BusMaster- SpecCycle- MemWINV- VGASnoop-
ParErr- Step
ping- SERR- FastB2B-
Status: Cap- 66Mhz- UDF- FastB2B- ParErr- DEVSEL=slow
>TAbort- <TAbort-
<MAbort- >SERR- <PERR-
Interrupt: pin A routed to IRQ 11
Region 0: Memory at e5000000 (32-bit,
non-prefetchable)[size=16M]
Region 1: I/O ports at e800 [size=256]
Expansion ROM at <unassigned> [disabled] [size=16M]
The card has only 2 M - and this incorrect detection makes
problems in use mtrr under XFree4.x .
Is it hardware problem or error in PCI detection routines ?

Look at http://www.erlenstar.demon.co.uk/unix/faq_2.html#SEC14
maybe this can help you.

Yes and no. It might solve his zombie problem, but what about that
outrageous VSZ and the locked memory? Useful info would be:
/proc/5025/status
/proc/5025/stat

That strange line is extremely rare. Actually it's the first time I see it and
I was unable to reproduce. And since it's a zombie it just didn't live enough
to type "cat /proc/....". I think there is a race somewhere. I don't know if
it's dangerous of if it only accects /proc reads sometimes ?
Bye.
