SigTerm URBackup 2.1.16 client - Debian 8.9

Hi

We regularly have sigterms with backups and we do not understand why.

The client is version 2.1.16 on a debian 8.9 and a kernel 3.16.0-4-amd64 # 1 SMP Debian 3.16.43-2 + deb8u3

root @ sd-89425: ~ # service urbackupclientbackend status
● urbackupclientbackend.service - UrBackup Client backend
Loaded: loaded (/lib/systemd/system/urbackupclientbackend.service; enabled; vendor preset: enabled)

Sep 04 21:57:15 sd-89425 systemd [1]: urbackupclientbackend.service: Failed with result ‘signal’.

Here’s what we do in the /var/log/kern.log:

Sep 4 21:57:15 sd-89425 kernel: [197.881107] file indexing [2739]: segfault at 0 ip 00007f82f5091049 sp 00007f82edff7528 error 6 in libc-2.19.s
o [7f82f4fff000 1a1000 +]

The client stops and can not perform backups.

On the interface:

Can you help me ?

thanks in advance

Could you capture a core dump? (I am assuming you are using the binary client?)

Does this version support the parallel hashing beta option?
Every time I enable the option it will run for a few hours and then I get ‘exited on signal 11’.
Forcing me to restart the process manually.

I have the option off again now and it just keeps running without any issues.

And it won’t get fixed until I get crash dumps or stack traces for that :wink:

Not the reason.

No problem. I’ll see what I can do.
