xl2tp 100% CPU on Centos 7.4 #144

Closed amasse76 closed 5 years ago

amasse76 commented 6 years ago

Hi,

I created a L2TP VPN connection with NetworkManager-l2tp. On CentOS 7.3, all work fine but the same configuration on CentOS 7.4 bring about 100% CPU on a thread ( after few seconds/minutes).

the xl2tpd version is v1.3.8 (from epel repository)

I tested to compile the 1.3.10.1 version but I have the same issue.

Regards Anthony

Are the logs (after you have enabled debugging) showing anything?

The 100% CPU arrives after

The computer is busy only xl2tpd. Many services and programs do not work correctly. Please, tell me how to use xl2tpd, because, there are no other alternatives ...

Regards, Oleg.

P.S.: I update kernel from elrepo to... Linux beta.ok 4.17.13-1.el7.elrepo.x86_64 #1 SMP Mon Aug 6 14:16:00 EDT 2018 x86_64 x86_64 x86_64 GNU/Linux ...and this problem was solved. xl2tpd (1.3.8) used 0% cpu. Sorry for the trouble and thanks for the xl2tpd.

removed xl2tpd package and did make; make install from latest sources. The issue is the same

lucad commented 1 year ago

Thanks with previous post of Oleg, I upgraded to kernel 6.5.5-1.el7.elrepo.x86_64 https://www.howtoforge.com/tutorial/how-to-upgrade-kernel-in-centos-7-server/ No more this issue! Note: However there is a new issue about cpu high usage, but related with scsi_eh_1 cpu ~ 50% usage. I run the centos in a vmware vm,
