WAN DHCP lease renewal causes configd.py error

[yuriqq]

Hello,

I'm running OPNsense 22.1.3-amd64.
My setup is as follows:
The OPNsense router is directly connected to a CPE device and the ISP is handing out IP addresses via DHCP.
It seems that every 10 minutes OPNsense renews the DHCP lease on the WAN interface.
After a few days of operation an error occurs every time the lease is renewed and the WAN connection drops for a few seconds.
The log shows this error:

Code: [Select]

2022-03-23T14:17:48   Error   configd.py    unable to sendback response [OK ] for [interface][linkup][['start', 'igb0']] {ec992202-d926-4a5e-96f6-0419c89a79f5}, message was Traceback (most recent call last):   File "/usr/local/opnsense/service/modules/processhandler.py", line 202, in run     self.connection.sendall(('%s\n' % result).encode()) BrokenPipeError: [Errno 32] Broken pipe
I can also trigger this error when I go to "Interfaces -> Overview -> WAN interface" and click on "reload" in the DHCP row.
If I reboot the router the problem goes away, but it will start happening again after a few days.

Here is a longer excerpt from the log:

I can't say for sure when the problem started, but it was definetly after upgrading to 22.1.

I'm not sure what causes this and how to debug this problem further.
So I hope that somebody might have an idea what to do.

Thanks in advance.
