Task execution failed in Qlik NPrinting.

[balajibc64]

Hi, we are generating report in Qlik NPrinting. We configured all the task and its working fine. Every task will reload and complete within 2 or 3 mins. 

Last week, suddenly few task keep on running and not completed. So I abort the task and restarted the Qlik NPrinting server and reload the task working fine. 

Again today, faced the same issue and  again I restarted the server its working fine. 

How to find the root cause? What are all the things need to check? Please suggest. 

Using latest Version only May 2023.

@balajibc64 I would suggest checking the Nprinting task log for the error message. Also, cross check the time of the failure in the task with windows event logs. Do they fell on the same days around the same time? Also, is it a Qlik Sense connection or QlikView connection to the source app? Check your Qlik Sense server and or QlikView server at the time the Nprinting task fails to ensure those servers are working properly. But the Nprinting task log and Engine log would be the first place to start.

[balajibc64]

@Lucas_Gatling ok I will check. Yes it happened on Tuesday morning around 6.15 am. After 2 weeks, again on Tuesday same time around 6.15 am. 

Already I checked the windows log, there is no clue on this. 

[Lucas_Gatling]

@balajibc64  ok so yes definitely check the task log and Nprinting Engine log along that timeframe. Those logs should produce error messages that will provide more insight on what could be causing the failure.

@balajibc64 I'd also look if there is something happening on Tuesdays around that time that could be interfering with the task execution...

[balajibc64]

Hi @David_Friend @Lucas_Gatling  I have checked the NPrinting Engine logs, Issue was found on Tuesday morning around 7 AM, but there is some locking error happens on Monday late evening around 9 PM. 

From Logs I found this error message, 

"Obsolete allocation message rejected before requesting the lock"

This error message showed in the engine logs, from Monday evening around 9 PM that too  before the issue day. Other days I didn't see this message anywhere.

[David_Friend]

@balajibc64 I recommend using MS Excel to open your log file in, so it can format the logs to read, otherwise NPrinting logs are far too long to understand...

Did you notice that message right at the beginning:

Enable Push from Server is enabled. This option is incompatible with NPrinting Server and Cluster connections and can cause severe delays.

[balajibc64]

Hi @David_Friend Yes. What is that mean. Also I found this statement too. 

Obsolete allocation message rejected before requesting the lock

[balajibc64]

Hi @David_Friend fyi, as you mentioned the statement "Enable Push from Server is enabled. This option is incompatible with NPrinting Server and Cluster connections and can cause severe delays".

I just checked the log file, This statement I can see all the days not only the issue day. But this statement is "Obsolete allocation message rejected before requesting the lock" seeing only that particular day.
