[SOLVED] NetworkManager.service: Failed with result 'core-dump'

NetworkManager started to crash on me recently. The problem emerged for the first time on April 19th after I upgraded to linux 4.16. It happens almost every day ever since. Any ideas?

Apr 25 21:38:24 plamen NetworkManager[885]: <error> [1524717504.4506] libsystemd: Assertion 'client->request_sent <= time_now' failed at src/systemd/src/libsystemd-network/sd-dhcp-client.c:1404, function client_set_lease_timeouts(). Aborting.

This causes the machine to completely lose the network.

Something odd w/ your system time? Big skew against NTP?

=> Check the the journal context of the incident.

Re: [SOLVED] NetworkManager.service: Failed with result 'core-dump'

Wow, you are on to something! When I read your post it hit me like a hammer. I instantly remembered that I recently changed my /etc/ntp.conf - added the local pfSense in the server's list.

# ls -l /etc/ntp.conf 
-rw-r--r-- 1 root root 722 Apr 19 10:02 /etc/ntp.conf
#

The date matches with the date when I started having this problem. Bash history shows that I also did:

systemctl enable ntpd.service
systemctl enable ntpdate.service

I disabled both of them to test it for a few days. If there are no issues I will enable them one by one to identify which service is causing all this mess.

Very good call. Thank you very much!

How do I do that?

Just check your journal for the incident and look at the logged events around (notably: before) it for anything suspicious (especially ntp related messages ;-)

Re: [SOLVED] NetworkManager.service: Failed with result 'core-dump'

I have done that. I see nothing relevant. I was not sure what you meant by "context of the incident".

It goes like this:

1. Reboot

2. After 1h and 45 min  I get this:

The same snippet repeats 8 times every 1hour and 45min.

3. On the 9th time it crashes:

Re: [SOLVED] NetworkManager.service: Failed with result 'core-dump'

Things that happen briefly before the assert but are not necessarily related to networkmanager.
The assert fails because a lease request seems to have been sent in the future, so either there's a problem w/ the dhcp server or the local time gets set back (or there's a bug in NM, but i'd expect more complaints in that case ;-)

However: there's "dhcpcd" and "dhcp4" so you seem to run dhcpcd and networkmanager concurrently?

systemctl list-unit-files --state=enabled

In case: don't.

Yes, dhcpcd.service is enabled. Are you saying that if NetworkManager is running and taking care of the network, dhcpcd.service should not be running?

Re: [SOLVED] NetworkManager.service: Failed with result 'core-dump'

Yes, precisely that. The concurrent lease requests also explain the error.
Disable dhcpcd or read up to maintain different interfaces with different network managing services (what though is usually pointless - pick one service and stick with that)

Re: [SOLVED] NetworkManager.service: Failed with result 'core-dump'

After three days uptime and no crashes I think we have a solution.

systemctl mask dhcpcd.service

Thanks seth!

You should™ not have to mask the service - unless you've enabled it, it should™ no start automatically, so disabling if would be sufficient.

Re: [SOLVED] NetworkManager.service: Failed with result 'core-dump'

Yeah, you are right. I did overshoot with "mask" and that was intentional. I wanted to make sure dhcpcd does not get started by some other service and it does not get in the way. I made three trips to my office last week because of this crash and I did not want to make a fourth one. I have not tested what happens if I only disable dhcpcd and this is why I did not provide it as a working solution. On the next reboot I will unmask and disable it to see if this is going to be sufficient. My guess is it will be.
