When the Thick Client has the -HL7LISTENER, and a user relaunches, the Thick Client crashes. This issue can be fixed in the INI settings for the Thick Client. In the INI settings, locate the {{HL7ListenerCreationRetrySeconds}} setting. This setting controls how long the system will retry to create the listener when the Client is started. If this value is set too low, the previous crash will reoccur. If this setting is set higher, there will be no impact unless the listener cannot be created. In this case, the client will crash when the amount of time specified has elapsed. This will most likely happen if the port the listener wants to use is already taken.
