scp gives Bus Error

MikeL_4 — Sat, 22 May 2010 16:06:33 GMT

I am able to log into 11V3 server via ssh with no problem...

But when I try to do an scp, either to or from the server I am getting the following error:

=>scp ./test.sh labserv1:/tmp/test.sh
Bus error(coredump)
lost connection
=>

Not sure where to look for the cause, if anyone can give some direction...

I did try to upgrade Secure Shell but that didn't resolve issue...

Hi Mike:

You might see if you have patch PHCO_40072. If not, try applying it. The patch notes indicate that "An ssh login sometimes does not behave as expected."

Regards!

I first downloaded the suggested patch, and running the create_ depot_hpux.11.31
Also failed with a core dumpâ ¦.

I created the depot on another server, but it told me it is already installed..
NOTE: The fileset "PHCO_40072.CORE2-SHLIBS,r=1.0" is already installed.

>Bus error(coredump)

What does "file core" show for the two cases?
You may have a kernel config problem if two different executables are failing.

>root:>./create_depot_hpux.11.31
Bus error(coredump)

Which is failing here?

>it told me it is already installed.

You could use "swlist PHCO_40072" to check that.

check if any file system is full ...i am guessing.

No file systems are 100% Full:

Note sure if the last attachment came through correctly...

I've attached core from scp error: scp.core

MikeL_4 — Sun, 23 May 2010 00:15:15 GMT

I've attached core from the create_depot_hpux.11.31 error:

>strings command on core files from scp and create_depot_hpux.11.31

This is next to useless. Though it does seem to indicate that ksh is aborting. So your system seems really sick.
Again, what does file(1) show for each?

>I've attached core from scp error: scp.core

Even more useless. A corefile is useless except on your system. Only gdb's packcore is transportable. Here a stack trace may be helpful.

That's strange. scp invokes disaster_files?
Or is disaster_files a ksh script that invokes scp?

>create_depot_hpux.11.31.core: ELF-32 core file - IA64 from 'create_depot_hpux.11.31' - received SIGBUS

You might want to do a swverify to see if ksh has been corrupted.

When did everything last work? And kernel parm changes?

Re: scp gives Bus Error

MikeL_4 — Sun, 23 May 2010 20:40:11 GMT

Disaster_files is a script that runs weekly out of cron, collects certain files and information, then scpâ s the data back to a management server for storageâ ¦ This was probably run last when I did the file on the core file, thus thatâ s why it showed up in the outputâ ¦ I just ran it again and it gave:
root:>scp ./test.sh labserv1:/tmp/test.sh
Bus error(coredump)
root:>file ./core
./core: ELF-32 core file - IA64 from 'scp' - received SIGBUS
root:>

I ran the swverify, and this server has big problems, looks like a rebuild of this server is in orderâ ¦

"/root/.sw/sessions/swverify.last".

There was no changes made to this server, it wasup and running just fine, when someone in the Operations center powered it off my mistake, and this is the resultâ ¦

Most likely. Or a restore of an ignite image.

ERROR: "osglbhp1:/": 40 software selection(s) are corrupt.
ERROR: "osglbhp1:/": 1 check scripts failed.
ERROR: "osglbhp1:/": The software dependencies for 156 products or filesets cannot be resolved.

I'm surprised about the "dependencies" issue.

>ERROR: "osglbhp1:/": 1635 files had errors during this operation.

You may want to look closer at this to see if anything missing or bad permission.

>powered it off my mistake, and this is the result

Yes, that could happen. Any fsck(1m) errors?
