The pear file, including the custom annotators that are associated with a collection, is running in a collection-specific, fenced box. The fenced box is a separate process called cas processor. In order to change the JVM heap size for that process, you must modify the following configuration file: NodeRoot/master_config/colID_config.ini Within the file, search for an expression such as: sessionN.type=casprocessor to get the session number for the current collection’s cas processor. After heaving the session number, change the heap size in the following setting: sessionN.max_heap=size in MB The default heap size is set to 200 MB. Be careful with increasing that heap size. For additional help, see the memory recommendations in the OmniFind installation guide.
