I had this exact issue. Running the suggested command resolved the issue.
I an curious as to how I can prevent this in the future. Any indication to what has caused this?
@Teeuwis, Hi!
Since the cause is not clear yet, we need additional information about the issue. When you face the issue again, please contact Plesk technical support. But please do not apply the solution, let us gather required information first.
Hello,
I have the same issue, but it does not help. I can not write a ticket because my plesk version is for third party, and unfortunatly they give not such a support for VPS.
Can I do anything else? I have found the solution
https://support.plesk.com/hc/en-us/articles/115000224773-Plesk-is-not-accessible-Can-t-open-or-create-shared-memory-by-shm-name
for the next ;)

# plesk installer --select-release-current --reinstall-patch --upgrade-installed-components
didn't yield any solution
Kindly help me the solution
Thank you

Its a NIGHTMARE!!!
Within the last 3 Month, Website got 2x offline because of this bug.
I have no blog with a few visitors, i have many customers using my SaaS Application day and night!
And you tell me
Cause
Not clear.
I am using Plesk more then 10 years now, but this problem is a bit new ...
Never had this problem before.
After first server crash and inaccessable Plesk, i turned off the
'automatic updates' function,- but as you see, that did not solve the problem.
Hello @Julian,
I would suggest trying this article.
In case it would not help, consider submitting a request to Plesk Support.
I experience the same message since a restart of the server today. I told my provider to fix the problem. Currently I stuck here and have no access to plesk, wonderful :/
@Daniel Bickel
If your server provider is Strato, then it is possible that you have hit the OpenVZ bug. Please refer to this article: https://support.plesk.com/hc/en-us/articles/115000224773-Plesk-is-not-accessible-Can-t-open-or-create-shared-memory-by-shm-name
