kernel: splitlog segfault at 0 ip error 4 in libc-2.28.so
I refer to the post (linked below) from 3 years ago that myself and another have commented on. The new posts on that thread have not appeared in the activity log in the forum right panel nor is it ranked at all in posts under Installations and Updates so I'm hoping this new post will boost it with a view to getting some feedback on it.
Here is the text I posted on the thread above regarding the segmentation fault "error 4 in libc-2.28.so". Also commented on by Allen Daniels who is experiencing the same issue.

I see that this is an ancient thread, however I've just picked up this error in our log files and not entirely sure how long it has been going on for, it appears in every hourly report.

The fix in the last post is not clear enough for me to implement a fix.
Can I get some advice please?
Thanks!

I did reply to the other post with some clarification on this - does that help the situation at all? If not, we'd likely need to see a ticket as I don't have any other recent reports of this behavior.

I have the same issue since the 23th updates;

Our team did identify an issue yesterday with this and we're working on this through case ZC-12792. I've linked the developers this thread as well and you can check this guide for a fix:

Thanks, cPRex . I've had no issues since updating via the instructions in that article. All looks good.

I have an issue after following the tutorial;
It seems that the packages is unavailable;
# rpm -e --nodeps ea-cpanel-tools
# dnf install ea-cpanel-tools --disablerepo=cl-ea4

Thanks again.

dnf clean all; dnf makecache
then try it
The replacement package came from a cPanel repository and not a CL repository I think. So you'll want to make sure your system is aware of latest packages available from all of the repositories.

I confirm that applying the suggested fix works on CL9.5 however any subsequent dnf update command will reinstall the old package.

Radu,
I see that as well. However, if you had already followed the instructions in the article, the proper directory would have been created. So I don't think there is an issue now. I haven't seen a single segfault since the daily update replaced the cpanel-provided ea-cpanel-tools-1.0-107.118.1.cpanel.x86_64 with the CL-provided ea-cpanel-tools-1:1.0-104.el8.cloudlinux.x86_64 late last night/early this morning on my machines.

Mike,
Indeed, you are right! Although this solves the problem for now, leaving the CL-provided package in place leaves the possibility of similar new problems in the future, if the CP-provided package changes significantly.
0 -
Quick update: It appears that the updated version of the package is actually available in CL testing repo.
To get it installed on CL9.5:
dnf upgrade ea-cpanel-tools --enablerepo=cl-ea4*1 -
i see this is resolved now so future EA builds should not be experiencing this issue. Let me know if you're still seeing problems!
0 -
I confirm that after upgrading from cl-ea4 testing repo the issue is gone.

Yeah I still have issues:

Could someone please clarify, we're on CL8.
Thank you!

bloatedstoat - I confirmed that is working on a test machine, so you may need to submit a ticket with us or CloudLinux so we can do some testing directly on your system.
