adb64 can not open core file over 2GB

[Alexey Roytman]

On the following system:
HP-UX ring B.11.11 U 9000/800 1868900601 unlimited-user license
The original adb64 can not open core file of 64-bit application that is over 2GB.

adb64 ./hyperroll $TMPDIR/core.org
PA-64 adb ($h help $q quit)
cannot open `/hyperroll/run/alexey/tmp/core.org', errno = 72, Value too large to be stored in data type

When I use the adb64 from the patch PHCO_31592, ir reports something different:

~/src/hpux11/patches/adb-open64/adb-64 ./hyperroll $TMPDIR/core.org
adb: warning: /hyperroll/run/alexey/tmp/core.org: Unknown errno: 72.
adb: warning: /hyperroll/run/alexey/tmp/core.org: Unknown errno: 72.
adb: warning: /hyperroll/run/alexey/tmp/core.org: Unknown errno: 72.
adb: warning: /hyperroll/run/alexey/tmp/core.org: Unknown file type.
adb: warning: File '/hyperroll/run/alexey/tmp/core.org' is not a memory file.

Both of adb64 do not work.

The core file size is 2,239,305,600 bytes.

Please do not recommend other debuggers (q4, gdb, etc).

I've traced it by "tusc" tool, and have seen the following calls:

open("/hyperroll/run/alexey/tmp/core.org", O_RDONLY|O_LARGEFILE, 070100) = 4
fstat(4, 0x7f7f1750) ERR#72 EOVERFLOW

what does

what `which adb64`

return?

What was this application written in?

What compiler was used?

You need to bring your machine upto Dec 2004, and upgrade aCC to at least A.03.52:

what `which aCC`
/opt/aCC/bin/aCC:
$Revision: 92453-07 linker linker crt0.o B.11.16.01 030316 $
HP aC++ B3910B A.03.52
HP aC++ B3910B A.03.52
HP aC++ B3910B X.03.37.01 Language Support Library

Also, what are your kernel parameter settings?

kmtune

Sorry, I do not *need*. Further versions of C++ compiler are separate products, and should be *bought* (there is no upgrade).

Also, we expect that adb64 is not a part of aCC bundle. As I've seen from the PHCO_31592, our expectations are right, and adb should be fixed.

My tries with library interposing of open() and fstat() functions (LD_PRELOAD) didn't catch for adb64 binary.

[Alexey Roytman]

Full kmtune output attached.

I think you were interested in maxdsiz*:
maxdsiz 0x80000000 - 0X80000000
maxdsiz_64bit 0x300000000 - 0X300000000

[harry d brown jr]

You are applying an 11.23 patch (PHCO_31592) on an 11.11 machine?

[Alexey Roytman]

No, I can not apply this patch:
1. OS version does not match
2. The patch does not fix the problem fully

I've just extracted binaries from the depot file (using "tar -xf ...").

[harry d brown jr]

I'd bring aC++ up to 3.63: http://www2.itrc.hp.com/service/patch/patchDetail.do?BC=patch.breadcrumb.main|patch.breadcrumb.pdb|patch.breadcrumb.search|&patchid=PHSS_32508&context=hpux:800:11:11
and the runtime to 3.61: http://www2.itrc.hp.com/service/patch/patchDetail.do?BC=patch.breadcrumb.main|patch.breadcrumb.pdb|patch.breadcrumb.search|&patchid=PHSS_32573&context=hpux:800:11:11

If it continues to have issue with adb, then I'd open a support call with HP.

As I've told above, A.03.13 is a last patch. The later patches (and the one that you've recommended, too) are other products, and if I want to install them, I should buy later version of compiler.

Also, can you explain *exactly*, how aCC and C++ runtime bundle affect adb64 behavior ? adb64 does not use dependant libraries (ldd shows none, chatr says it's a shared executable, but not dynamically linked).
I want to know *exactly* *how* these patches may fix the problem. Because as far as I understand (and I may be wrong), that seem to have no effect.

[harry d brown jr]

If you have all the answers then enough said!

Maybe, you're right, and the only solution is to open an HP bug fix request.

[A. Clay Stephenson]

As a workaround, I would use dd and write the first 2GB or less to another file and then start adb on that file. I rather doubt that you need that much of the core image to do a stack trace.

[Alexey Roytman]

This was a first thing I've tried :-) This does not give me any nesessary information (the application has over 40 threads).

[Duncan Edmonstone]

Do you have this patch:

PHCO_28774 s700_800 11.11 nadb(1) enablement

This certainly adds a newer version of adb to your 11.11 system for both 32 & 64 bit cores. Doesn't actually indicate whether it fixes your problem though... I guess its worth a try.

I've downloaded NEWADB11i.depot, installed nadb, and installed the patch described above. Nothing changed:
