Limiting the use of resident memory by the application

You can configure a limit on the application's use of resident memory. By default, the limit is set automatically.

Setting a limit in the Web Console

In the Web Console, you can enable or disable the resident memory usage limit in the policy properties (Application settings → General settings → Application settings, Advanced application settings section).

In the Advanced application settings section, the Configure memory usage link opens a window where you can configure the resident memory usage limit (see the table below).

Setting a limit on the command line

In the command line, you can configure the resident memory usage limit using the MaxMemory setting in the kesl.ini configuration file.

The MaxMemory setting can take the following values:

off – the resident set size is not limited.
<value>% – a value between 1 and 100, expressing a percentage of memory.
<value>MB – a value in megabytes.
lowest/<value>%/<value>MB – the smaller value between the value as a percentage and the value in megabytes.
highest/<value>%/<value>MB – the larger value between the value as a percentage and the value in megabytes.
auto – up to 50% of available memory, but not less than 2 GB and not more than 16 GB.

Default value: auto.
