Description HIDEO YAMAUCHI 2016-10-31 00:36:52 UTC

Description of problem:

Memory increase of the systemd process.

The systemd(pid=1) process continues increasing the memory.
Similar problem is reported in the community of systemd, but a new version of systemd seems to be necessary for the solution to problem.
 - https://github.com/systemd/systemd/issues/2614

Version-Release number of selected component (if applicable):

[root@rh72-01 ~]# uname -a
Linux rh72-01 3.10.0-327.36.2.el7.x86_64 #1 SMP Tue Sep 27 16:01:21 EDT 2016 x86_64 x86_64 x86_64 GNU/Linux
[root@rh72-01 ~]# rpm -qa |grep systemd
systemd-python-219-19.el7_2.13.x86_64
systemd-219-19.el7_2.13.x86_64
systemd-libs-219-19.el7_2.13.x86_64
systemd-sysv-219-19.el7_2.13.x86_64


How reproducible:

The phenomenon reappears by carrying out the following test scripts which I prepared for beforehand.
This is a script connecting with local host (rh72-02) in ssh.

------test.sh----
#!/bin/sh
while [ 1 ]; do
   ssh rh72-01 ls
   sleep 1
   echo "test"
done
------

Steps to Reproduce:
1. Watch systemd process by top command.
2. Carry out test script.

Actual results:

The RSS of the systemd process that I watched by top command continues increasing.

Expected results:

It cannot be necessary to continue increasing the RSS of the systemd process that I watched by top command.

Hideo Yamauchi.

There are many memory leak fixes in systemd-219-30.el7. Could you please try that build?

Comment 3 Jan Synacek 2016-10-31 08:31:58 UTC

I forgot. You can find it here: https://copr.fedorainfracloud.org/coprs/lnykryn/systemd-rhel-staging/

Comment 4 HIDEO YAMAUCHI 2016-10-31 08:42:51 UTC

Hi Jan,

Okay!

I try it.
In addition, I inform you of the result here.

Best Regards,

Hi Michal,

I was not able to find rpm of systemd-219-19.el7_2.14.

Where should I download rpm of systemd-219-19.el7_2.14 from?
Or should I use rpm of Fedora as Mr. Jan says?

Best Regards,
Hideo Yamauchi.

Comment 7 HIDEO YAMAUCHI 2016-11-01 00:37:48 UTC

Hi Jan,

I started confirmation with the package which you told.
I confirm it in consecutive movement until the weekend and report a result.

You can't get it from anywhere because this version of systemd was not released yet.

Feel free to test packages from COPR as they also contain a fix.
