Question

com.apple.xpc.launchd[1]: (org.net-snmp.snmpd[2601]) Service exited due to signal: Abort trap: 6

iMac (27-inch, Late 2012); 2.9 GHz Intel Core i5; 24 GB 1600 MHz DDR3.

OSX 10.11.6

net-snmp version 5.6.2.1

Net-snmp is crashing and restarting every few minutes - see graph trace of snmp engine uptime below, it's never up for even 20 minutes; generally no more than 10. The machine itself has not been restarted in the graph period below. Issue has been happening for a while now, prior to more than one reboot (i.e. a machine restart does not fix it).

Each restart of the snmp engine corresponds to entries like this in the logs:

27/07/2016 11:07:37.243 snmpd[2601]: snmpd(2601,0x7fff73180000) malloc: *** error for object 0x7f92d280ff60: incorrect checksum for freed object - object was probably modified after being freed.

*** set a breakpoint in malloc_error_break to debug

27/07/2016 11:07:37.243 diagnosticd[141]: error evaluating process info - pid: 2601, puniqueid: 2601

27/07/2016 11:07:37.244 com.apple.xpc.launchd[1]: (org.net-snmp.snmpd[2601]) Service exited due to signal: Abort trap: 6

27/07/2016 11:07:42.656 ReportCrash[2621]: Saved crash report for snmpd[2601] version 151 to /Library/Logs/DiagnosticReports/snmpd_2016-07-27-110742_Antony-iMac.crash

The snmpd then restarts with a fresh process ID, as you'd expect.

A brand new MacBook Pro running the same OSX version and the same net-snmp version has no such issues.

Any ideas or suggestions for a fix? Is it possible to reinstall the same version of net-snmp, maybe?

iMac, OS X El Capitan (10.11.6)

That process doesn't run at all by default. Do you know how and why it was enabled?

It's running because I enabled snmp, in order to be able to monitor the machine's performance from a remote monitoring application.

On the MacBook Pro, as mentioned, it runs without issue.

And yet, today, initially the snmp daemon ran fine from first boot, until I restarted the machine just about 10am for unrelated reasons.

Post-restart, back to the instability. I've tried to think what I was doing differently pre-restart and the only thing I can think of is, I didn't have my iPhone connected before the restart. Everything else was the same as far as I can recall. I have since disconnected the iPhone however, and the snmp daemon is still bouncing around.

Please read this whole message before doing anything.

This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.

The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.

Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem.

Note: If FileVault is enabled in OS X 10.9 or earlier, or if a firmware password is set, or if the startup volume is a software RAID, you can’t do this. Ask for further instructions.

Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.

The login screen appears even if you usually login automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.

Test while in safe mode. Same problem?

After testing, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of the test.

Thanks Linc.

Reading your suggestion, it occurred that a recently-added piece of software that loads at startup is DialPad.

It does occasionally fail to start correctly however; including this morning (crashed at 08:57).

I noticed it hadn't loaded properly around 09:30 so restarted it...

I then added it into monitoring as a monitored process (purple line, lower graph) and quit the application at 10:14, before restarting it just before noon.

As you can see, a striking "coincidence"!

I guess I'll delete and reinstall DialPad, as this looks an awful lot like a smoking gun - thanks for the previous post, the "third-party software that loads automatically at startup" comment was just the prompt I needed, I think.

I'll reinstall and see if that cures it.

I am now confident the problem was a corrupted install of DialPad.

The ops notes on the graphs (the purple flags and vertical lines) represent:

11:52: DialPad restarted

12:19: DialPad deleted from Applications *but settings files not cleared out*

12:25: DialPad reinstalled from fresh .dmg download - however, it knew who I was, i.e. was still using the old settings files.

13:41: DialPad deleted again, but this time also all DialPad files removed from ~/Library/Application Support/, ~/Library/Preferences/, and ~/Library/Caches/

14:01: DialPad reinstalled, reusing previous .dmg - this time it did not know who I was so I had to log in.

Thanks for the pointers!

Correction:

"I am now confident the problem was a corrupted install of DialPad."

No, I am now confident that the problem is simply DialPad. The reinstall was OK until next boot, after which the snmpd restarts resumed and are reliably linked to DialPad running / not running. Additionally the same issue is now seen on the MacBook (possibly an update to DialPad?). DialPad running = snmp broken. DialPad not running = snmp fine.

Time to get on to DialPad support...
