Upgrading systemd. Need downtime?
by james000 from LinuxQuestions.org on (#58SFF)
Hello,
On my RHEL 7.2, I am seeing systemd is consuming 98% of memory. I see this note, which explains this bug - https://access.redhat.com/solutions/4401881
And I see lot of core files under /var/spool/abrt
Code:[root@rhel7.2 ~]# systemctl |grep "of user root" |grep "abandoned" | wc -l

74 root 20 0 0 0 0 S 0.3 0.0 170:54.17 rcuos/0So it looks like I need to install systemd-219-30.el7.x86_64, instead of existing systemd-219-19.el7.x86_64. I am able to download systemd-219-30.el7.x86_64
It is production server, so being more cautious. Would I install it (yum install systemd-219-30.el7.x86_64) or upgrade it? Can it impact something on server then downtime is needed?
Thanks
