This optional key name specifies the amount of memory in Kbytes that the server should use internally. Valid values are numbers in the range [8 to 4096] and it has a default value of 64.

An appropriate value for InternalMemorySize can be determined by examining the statistics on the Equinox server screen. The screen shows the highest usage since the Equinox server was started (it is reset each time the application is unloaded).

You should try and maintain InternalMemorySize so that its value is about 32(K) above the highest recorded usage.
