Failed to allocate new QlikView Engine - Max usage reached

Hi all,


We are occasionally getting this error message.


Information: Failed to allocate new QlikView Engine. Retrying! Max usage reached. Current usage count=7 of 7 (of type non-reader).


I have checked the Distribution Services configuration:


Max number of simultaneous Qlikview engines for distribution is set to 7

Max number of simultaneous Qlikview engines for administration is set to 20.


The machine on which QV is running is 12 core on 2 CPUs. Initial investigation in the community suggested increasing the number from 7 to possibly 10 but I just wanted your opinion as 7 is probably already relatively a high number.

Hi,

Thanks. Yes, that is the one I had come across before. Basically, they are suggesting to add and hence why I asked if adding to 10 should be ok (given the 12 cores). I'll probably try that out.

Thanks for your feedback.

Hi,

You need to do 9 and not 10. If you go over 10 you will need to change the Desktop Heap setting. Also, remember that Qlik isn't the only thing that uses a Comms Object.

Bill, do you however suggest that in the short term we set it to 9? We had some consultants a couple of months ago which had actually suggested we reduce it from 7 which I found strange to be honest. In the long but near term we'd like to review our job/scheduling as I believe that is the "core" issue. This machine is furthermore dedicated to Qlikview ... other than any windows server processes - there is nothing else using up any resources.

Hi,


I don't think setting to 9 will hurt you. If it does cause issues you will know right away.
