Resolved sw-cp-service failed start after server reboot

[merchadou.theo]

Since I restarted my server, I can no longer access plesk administration (ERR_CONNECTION_REFUSED). All my websites are still working.
I tried to restart all services

# /etc/init.d/psa start
Starting sw_engine service...                                         already started
Starting sw_cp_server service...                                      failed
Starting mysql service...                                             already started
Starting named service...                                             already started
Starting mailer service...                                            already started
Starting spamfilter service...                                        already started
Starting drweb service...                                             done
Starting apache service...                                            already started
Starting xinetd service...                                            already started

And when I launch the service only :

# service sw-cp-server start
D?marrage de sw-cp-serverd?: /bin/bash: line 1: 13869 Erreur de segmentation  /usr/sbin/sw-cp-serverd -c /etc/sw-cp-server/config

Server Details
Product Version: Plesk Onyx 17.8.11
OS version: CentOS 6.10

Thanks for your help.

Do you see anything relevant in /var/log/sw-cp-server/error_log ?

 

[merchadou.theo]

Nothing since the restart of the server...

 

[Monty]

Well, the service crashes with a segmentation fault. That is pretty bad and very unusual.
Is your server a VPS? Are you on Virtuozzo?
Did you check if you see anything relevant in /var/log/messages?

 

[merchadou.theo]

This is a dedicated server from SoYouStart.

when i start the services, i got these messages on /var/log/messages

Nov 22 20:16:22 ns395376 kernel: sw-cp-serverd[7088]: segfault at 6dc408 ip 00007fb88ebbec6f sp 00007fff8e448a60 error 4 in libnginx.so[7fb88ebb9000+6000]

Thank's for your interest,

libnginx.so library does not belong to Plesk but looks like it is preloaded on the system for some reason. I'd suggest you check it first.

 

[merchadou.theo]

Nothing on /var/log/nginx/error.log ...

Here is some information that may be of help :

# nginx -v
nginx version: nginx/1.16.1

# nginx -t
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful

ERROR: ld.so: object '/usr/sbin/libnginx.so' from /etc/ld.so.preload cannot be preloaded

Try to open /etc/ld.so.preload/lib64/libs.so or /etc/ld.so.preload file in any text editor and comment libnginx.so library:

#/usr/sbin/libnginx.so

Thanks for your help, it's working again, but why did this happen after the server was restarted, when everything was working fine before?

 

[IgorG]

For some reason libnginx.so library interferes with sw-cp-server libraries. To investigate these reasons I'd suggest you contact Plesk Support Team.

OK, thanks for your help. I appreciate it.
