Resolved Inconsistency detected by ld.so during Apache Reload/restart

[Pascal_Netenvie]

Hello,
Sometimes in the morning when some process restart apache (after log rotation or update) we have an error and Apache crash.
In apache log we see that :
Inconsistency detected by ld.so: ../sysdeps/x86_64/dl-machine.h: 523: elf_machine_rela_relative: Assertion `ELFW(R_TYPE) (reloc->r_info) == R_X86_64_RELATIVE' failed!

At this moment the only way to fix seems to restart server.

Do you have an idea about that ?

This server runs Debian 9 with 4.9.0-8-amd64 x86_64 Kernel.

Regards.

Did you perform a dist-upgrade there? In this case, the reason may be related to the uncompleted successfully dist-upgrade.
I'd suggest you check corrupted packages with:

# debsums -c | xargs -rd '\n' -- dpkg -S | cut -d : -f 1 | sort -u

BTW, is this Virtuozzo VPS?

 

[Pascal_Netenvie]

Thanks for answer.

No dist-upgrade performed on this server.
And debsums command not found by bash ...
And it's not a virtuozzo VPS, physical dedicated server.

 

[IgorG]

And debsums command not found by bash ...

# apt install debsums

 

[Pascal_Netenvie]

Yes already done, and runing ...

Result :
drweb-bases
fail2ban
linux-headers-4.9.0-8-amd64

plesk-php70-pdo
plesk-py27

[IgorG]

Hmm... There is no such thing on my server with Plesk.
I would try reinstalling the linux-headers package first.

 

[Pascal_Netenvie]

Ok, thanks.
Best process to do it (from you) ?

 

[Pascal_Netenvie]

In Apache log last crash on restart was after drweb-bases update ...

 

[IgorG]

Best process to do it (from you) ?

# apt-get install --reinstall linux-headers-$(uname -r)

 

[Pascal_Netenvie]

Ok, classic.
But :
Reinstallation of linux-headers-4.9.0-8-amd64 is not possible, it cannot be downloaded.

 

[IgorG]

uname -r is really returned 4.9.0?

 

[Pascal_Netenvie]

It return :
4.9.0-8-amd64

I have this in source.list :
deb Index of /debian stretch main contrib non-free
deb Index of /debian-security stretch/updates main contrib non-free
deb-src Index of /debian-security stretch/updates main contrib non-free

 

[Pascal_Netenvie]

Is it normal that i have this in apt sources on a 18.0.x plesk :

deb [arch=amd64] http://autoinstall.plesk.com/PMM_0.1.11 stretch all

 

[Pascal_Netenvie]

I have uninstalled drweb and plesk-py27 (old migrator) as it is packages from older Plesk versions.

 

[Pascal_Netenvie]

****, problem occured again this morning ...
First reboot don't solved the problem, and after a second reboot it was ok.
And always the same message in apache error log when we have 500 error :

Inconsistency detected by ld.so: ../sysdeps/x86_64/dl-machine.h: 523: elf_machine_rela_relative: Assertion `ELFW(R_TYPE) (reloc->r_info) == R_X86_64_RELATIVE' failed!

 

[Pascal_Netenvie]

Tonight we gonna upgrade Kernel and reinstall some packages.
I'll keep you i ntouch.

 

[Pascal_Netenvie]

Hello,
We upgraded Kernel to 4.9.0.16 last night and it seems it solved the problem.
Thanks for your help.
