NPrinting Task Warn or Fail error with internal connection time out

Sonja_Bauernfeind — Thu, 27 Aug 2020 07:14:03 GMT

NPrinting Scheduler service navigator timeouts may result in occasional Publish Task failure or 'warning' messages

Found in:

NPrinting June 2020 (also affects earlier versions)

Solution (interim workaround): Update and modify the NPrinting scheduler.config file

The following setting forces the internal NP scheduler/connection navigator to close when the requests from earlier tasks have completed. Essentially, this overrides the default behavior of leaving connections open. It allows memory to be released back to the system

stop the NPrinting Scheduler service
open the NPrinting Scheduler.config file found in "c:\program files\nprintingserver\nprinting\scheduler" (make a backup copy of the scheduler.config file before proceeding)
Within the Scheduler Options section: Insert the following line above the </appSettings> tag as shown in the image below

Save the file and close
Restart all the NPrinting services

Note:

This option has 3 values:
"0": that is the default value, means do not force a shutdown of currently opened resolvers/navigators (apart if there are other connections that needs to use system resources);
"1": force a shutdown of all opened resolvers/navigators (so all Sense apps/Qv documents opened) when the system is "idle" (i.e., when all the rows in admin/plan page have 0 requests);
"2": force a shutdown of all opened resolvers/navigator on a certain connection as soon as that connection reach 0 requests

Cause of this issue:

Tasks scheduled at different hours and the NPrinting connection navigators are found to be in timeout status within the NP scheduler service. Result that the NP connection navigator session to Qlik Sense was expired in turn causing the task failure or warning messages. (Further, selections were not cleared properly which lead to a false logging message that the issue was related to a bookmark/filter.)
