Nprinting 16: Not enough storage is available to complete this operation

Descriptive error logging that results in this issue:

• An NPrinting task fails to run normally for a specfic NSQ when the following message is observed in the NPrinting 16 log files" "Not enough storage is available to complete this operation" in Nprinting 16 Logs after a report task execution
• When attempting to save the NSQ file which contains the failing task, you may also get other messages such as: Access Violation or file cannot be saved

What causes this behavior:

• Duplicate filters
• Recipients
• Reports
• Jobs
• Tasks
• Schedules

Workaround Solution:

• After successfully executing and sending of emails, an error appears in the log: Error while executing the service. Retrying to execute. (Error: Not enough storage is available to complete this operation). 
• This error makes it impossible to distribute subsequent reports. 
• NPrinting attempts to execute the report task with the following logging messages: "Connection Closed" and after "Reloading QlikView NPrinting files" the error appear. "There was enough storage on the machine to complete the task"
• This error is due to limitations in Nprinting when NSQ (xml text file) file sizes become too large due to having to parse too many unnecessary and or duplicate filters, recipients, reports, jobs, tasks etc.
• The solution is to check for any existing duplicates in the designer configuration - filters, recipients and clean out the duplicates or unnecessary items mentioned above.

• This method decreases the NSQ size and the conflict should in turn resolve the issue as a result of file size reduction and the mitigated need to parse unnecessary filters and or other specified duplicate or unnecessary entities.

Best Practice:

• Limit and or reduce the number of unnecessary entities added to NPrinting
• These include:

1. Duplicate filters
2. Recipients
3. Reports
4. Jobs
5. Tasks
6. Schedules

• Split your NSQ in to smaller slices by copying larger QVWs and organizing the copies by department, region, city, country and/or organization etc. For example you may want to include certain reports for a specific department in your NSQ. This way you might have a separate NSQ for 'Sales.nsq, Executive.nsq, SeniorManagers.nsq. Ensure that you only keep the necessary and relevant reports and schedules for each new NSQ organized using this approach.
• NOTE: There is no specific file size limitation but reducing the NSQ file size as mentioned above will help to mitigate the issue.
