mmap failed for dld

[Van den Abeele]

Hi,
One of our customer experiences a problem with one of our applications. The application is correctly running since a long time on a HP 10.20 9000/813 and is failing on a 11.11 9000/813.
This 11.11 is a very new system over there and honnestly speaking I do not know if they installed patches.

It creates a core file and stops continuing the application. Making a strings on the core file, we are able to collect the following information :

B.11.11
9000/800

Does someone can advise us ?

Hi:

One possible reason for this error is insufficient swapspace. Use 'swapinfo -tam' to examine your space.

Regards!

I did face the same problem sometime back.
I am attaching a small C source to make the core readable to give us further clues.

Is your application using any threads?
Also what signal is the application catching?

In my case it was the application code that was offending by improper syncing using thread mutexes.

Hi,
Thanks for answer ... swapinfo is not found on the HP-UX 11.11 machine.
It exists on the 10.20 .....
Does this mean there is no swap .... ?
Thanks

Hi

If this is your application than doing only 'strings' on the core is the least usefull thing you could do. How about checking it with debugger?

How about 'file core' and 'what core'?

I guess you miss a shared library on that host.

Good luck

Hello,

swapinfo is found in /usr/sbin/swapinfo
and must be run by user root.

Strings on the core file does not give
any valuable info.

Try this command instead:

file core

It may show you what caused the core-dump.
(SIGSEGV .....)

As you have a core file I advise you to run
the debugger on it.

To get the call-stack do the follwing:

gdb executable core
(gdb) info stack

If the binary you are running on 11.11 is
compiled/linked on 10.20 it may be that it
used some API that has been changed.

Hi,
We'll try to recompile it on HP-UX 11.11 which seems to be the most easy solution.
We just have to find such an HP-UX 11.11 available. We are currently only running 10.20.
It is probably due to X25 or other stuffs which are differently "made" on 11.11.
At least our customer has such a system.

Hopefully, only a single module is concerned by this problem.

I'll let you know tomorrow as we just finished sending the pack to the customer which will download and let us compile.

Regards
Luc

Hi all,

I tried this morning (Friday instead of Thursday because my customer was slow to provide access to the source code ...) and unfortunately it failed due to dld reasons again.

Please find the message ... Any Idea ?
Thanks

Hi Luc

Just what it says:
You have no
/usr/local/lib/libbfd-2.11.2.sl
on the custommers host.
Install it and check again.
However this can be 'the first from the list', so after installing you can expect problems with missing another one.

Check where this library comes from? I guess its a part of a bigger package. Consult with the documentation baout the installation procedure.

Well, I was right. :)

Good luck
Adam

Check to see if /usr/local/lib is in your SHLIB_PATH (echo $SHLIB_PATH).

If not, add it:

SHLIB_PATH=$SHIB_PATH:/usr/local/lib;export SHLIB_PATH

[H.Merijn Brand (procura]

libbfd is from the GNU tree (binutils/gcc). Make a clean install from the latest gcc available for 11i (http://hpux.connect.org.uk/hppd/hpux/Gnu/gcc-3.2/ or http://h21007.www2.hp.com/dspp/tech/tech_TechSoftwareDetailPage_IDX/1,1703,547,00.html) and try again

Enjoy, have FUN! H.Merijn

[Van den Abeele]

Thanks to all of you.
We tried to recompile on a HP-UX 11.* system without better results. Honnestly, the customer did it on its own and I had no guarantee it was correctly performed. I got a copy of the stderr/stdout out of the compilation but I had some fears.

We finally recompiled the code on our system a 10.* one, installed the latest exe and it works fine ! This is Software and IT !

Thanks
