LSOF - when executing get core memory dump

Alex Grigore — Wed, 19 Oct 2005 09:51:47 GMT

Hi guys,

I work on a HP-UX B.11.11 RP server, 64bits.
In order to verify which applications open which ports, i installed LSOF from http://hpux.ee.ualberta.ca/hppd/hpux/Sysadmin/lsof-4.75/.

First, I installed version 4.76 - with interactive swinstall. Everything goes nice and smooth, but when i do
#lsof
I get "Memory fault(coredump)"
and a coredump file
-rw------- 1 root sys 886348 Oct 19 17:50 core

Uninstalled version 4.76 and installed version 4.75. The same memory dump occured when trying to call lsof.

Is there something I am missing?

Thanks and regards,
Alex.

do 'file core'

What signal are we catching.

You downloaded 32bit version of lsfo and you try to run it on 64bit OS.

Download it from here:

No no, it's not a depot file, it's a binary.

Just rename it to "lsof"
No installation required.

I'm getting the same thing.. but it seems that lsof alone with no options is giving me this issue.. anytime I use lsof with any options like -v or -? gives me the proper response without a core

Marco, it's because with "-v" option no actuall work is done there, only print out to the screen.

When it tries to analyzy the system, than you get the core, because all the memrory addressing is wrong, since it's 32bit binary.

Thank you Alex, Marco, Kent.

It works now - i renamed the file to lsof, make it an executable and i am able to get the needed info.

Regards,
Alex.

FWIW, I had a similar problem, so I downloaded the source and compiled it. Problem gone.
