RE: [nv-l] Netmon exited with signal 6

[James Shanks <jshanks@us.ibm.com>]

Scott --

Well, it looks to me as though gdb can only make so much out of the core and it just stops at the last line, the one you have highlighted in red, before the (gdb) prompt.   I don't like the fact that it's in libc -- that would indicate an OS-related  problem to me.  In any case gdb seems to return the prompt without giving any register data.  That's unexpected so the readcoreg program hangs.  Why it's doing that, I don't know -- not my area of expertise.   Nor is netmon.

This will have to be looked a by someone else, which is why sending it to support is the only recourse.

James, here is the output, I have no idea what it means, maybe you can assist. I do have a PMR open with support on the core. I have reported that I cannot run readcoreg. I'm not sure if you are allowed to help here or not, but maybe someone can.

readcoreg will sleep indefinitely if it  has a problem with the underlying gdb process.  I would try gdb natively from the command line, like this: . 
        gdb  /usr/OV/bin/netmon  core 
to see what his problem is

Also as a side note, I can't seem to run readcoreg against the netmon cores. 
  
I get a message saying "reading registers" and then nothing happens. I truss'd the process and it just says "sleeping" indefinately.

I'm confused, Scott. What release are you seeing this problem on? 

As far as I know, the only people who could already have 7.14 running would be part of the beta customer group.  Are you part of that? 

NetView 7.1.4 was otherwise just announced today for Business Partners and won't ship for general release for at least a week yet.  It's been in Verification longer than any previous release, and if most installations had been netmon die on signal 6, it wouldn't have shipped even now.  So I think this is a rare occurrence, though I could e wrong, since I don't work on netmon.  Even so, I thought there was a procedure for them to report their problems to development directly to avoid announcements like the one you just made. 

What went wrong?  Didn't the beta last long enough?

FYI - Netmon for NetView 7.1.4 is corein'g on signal 6 - you didn't mention what version you were on, but if it is the new one, it looks like it has a problem already.

It means you should call Support.  That is not normal.  As the man page for signal on AIX will tell you a signal 6 is SIGIOT or "abort process". 
If you are not up to current on NetView maintenance, especially for netmon, I would get some, and for that you should call Support

All,

I have added over 100 IP addresses into the seed file with "$" to force SNMP polling
Recycled netmon and I see that netmon kept exiting with signal 6

Do you know what does that mean??

Regards!
