Error code: x21

Internal designation: EC_NO_MEMORY

Description: There is not enough memory to complete the requested operation.

To identify the possible cause and the circumstances of the error, refer to the Dr.Web for UNIX log (by default, it is located in the /var/log/syslog file or the /var/log/messages file, depending on OS). Also, you can use the command drweb-ctl log.

Resolving the error

1.Increase size of available memory for Dr.Web for UNIX processes (for example, by changing the limits with the ulimit command), restart Dr.Web for UNIX and repeat the operation.

Note that in some cases the system service systemd can ignore the specified limit changes. In this case, edit (or create if it does not exist) a file /etc/systemd/system/drweb-configd.service.d/limits.conf and specify the changed limit value, for example:

[Service]
LimitDATA=32767

The list of available limits of systemd can be viewed in the documentation man systemd.exec.

Restart Dr.Web for UNIX by entering the command:

# service drweb-configd restart
