Plesk is a highly efficient web server administration control panel. It is offered with the Windows web hosting platform. At times you may come across a situation where the Plesk control panel might not load.
If you are not able to login into Plesk, refer to the process mentioned below:
/usr/local/psa/admin/logs/httpsd_error_log
If you encounter the error message mentioned below, it means you are using more memory space than what is allotted to you:
[emerg] (22)Invalid argument: could not call shmget
In this situation, you have to increase the value of ‘shmall’ in the ‘/etc/sysctl.conf’ file. Edit this file and increase the value with the following command:
kern.sysv.shmall=shmmax/4096
In case you want the changes to get reflected right away, you can execute the command mentioned below:
sysctl –p
You will have to reset the psa service; this will enable you to access the Plesk control panel.
