It is certainly an issue segfaulting, thanks for reporting the bug.

I wonder if it is more about your special Hardware or your configuration for it.
The log is full of:
дек 03 22:50:04 hostname upsd[2401]: Can't connect to UPS [myups] (usbhid-ups-myups): No such file or directo

Unfortunately I found no pointer what is missing.

Could you reset the nut configuration and restart it.
And then go step by step to your config - mayby you can bisect the critical config part that triggers it.

Also asking for anybody out there who can to try to repdocue - adding Jon for that to unpack his UPS :-)

Changed in nut (Ubuntu):
status:	New → Incomplete

Hi guys,

this is very possibly a duplicate of #1483615
the error is probably due to an issue retrieving a string, and not handled in the driver code.
To confirm, please start the driver in debug mode using (as root):
/lib/nut/usbhid-ups -u nut -DDD -a myups
then
/lib/nut/usbhid-ups -u root -DDD -a myups

if confirmed, this was fixed upstream: https://github.com/networkupstools/nut/commit/f679a2820e49cbdec4138295de5e8947ee953a8a

However, as mentioned in the other ticket, the above fix has some negative impact.
this may in the end be due to another ticket (tied to udev and privileges application) logged by Charles Lepple. This privileges issues could lead to the string retrieval issue, causing these bugs.

All in all, adding the patch has more benefits than drawbacks

Sorry, i can not replay errors, now nut works all right (after reboot old server i915 P4-651 and workstation z97 i5)

In first installation nut and connect APC back-ups ES525 - nut not work and show
srv kernel: [10309.863851] usbhid-ups[11415]: segfault at 0 ip 00007fb58423ff37 sp 00007ffeb7276e98 error 4 in libc-2.23.so[7fb5840fb000+1bf000]

Now, after reboot computers - no error and nut work all right.
I reboot server after three days and ups work!
Then i check on workstation and ups work.

But in first 2016-12-03 not work.
Ups connect before nut installation.
What is changes: computers reboot with nut installation.
