Environment:

• NPrinting 16

Too many recipients and filters imported to .nsq using Import Task; Issue may occur even if import task has the option to "Remove old recipients". Filters are not automatically removed as they are not bound to the recipients. In addition, due to the number of recipients dynamically removing old and adding new recipients causes NPrinting Designer to hang or NPrinting Service to stop/crash.

Remove the imported recipients and filters imported during the project's Import Task and/or split the recipients/filters being imported in two or more NPrinting projects files (.nsq). The maximum number of recipients/filters depends on the environment and determining a baseline in the specific environment by trial and error would is recommended.
