You can increase the memory available to the eiConsole by adding or updating the eiConsole.vmoptions parameter in the configuration file in the install folder. Once this setting is changed, the eiConsole will have to be restarted for it to use the newly changed value. An example value is shown below to give the eiConsole access to 2560 Mbytes of memory.
Set the maximum RAM available to the application -Xmx2560m
