QVB Process Hanging

[bhelms]

We are having a problem with our reloads never completing. They just hang. We currently are allowing 6 reloads at one time. This problem seems to occur when more than 6 reloads are kicked off by publisher. Today we had 12 jobs running at one time. 6 should be running, and 6 should be waiting. The problem I am seeing however, is that only one of the jobs is actually running, but the server has 8 QVB.exe processes, all but one of them stuck (RAM never moving). I then have to kill all of the QVB processes, restart the QDS, and then kick off all of the jobs again. The other strange part is then I kick off all of the failed jobs (at this point was 17), and they all run fine. 6 run, the rest wait. It runs like it should. But I am having this problem every morning when the publisher starts the jobs. Anyone seen this before? We are on QV 11.20.12235.0.

Hi Brian,

I am very interested to find out if you errors have gone.

I will be ftping various log files to qlik support today for them to look into the problem.

Our SharedSection=1024,20480,768 and our max qv engines is set to 4.

Below is the error we are getting in the application eventlog:

Failed to create QlikView Engine..

Hi all,

FYI

we have changed the following registry key :

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\SubSystems\Windows

to:

%SystemRoot%\system32\csrss.exe ObjectDirectory=\Windows SharedSection=1024,20480,2048 Windows=On SubSystemType=Windows ServerDll=basesrv,1 ServerDll=winsrv:UserServerDllInitialization,3 ServerDll=winsrv:ConServerDllInitialization,2 ServerDll=sxssrv,4 ProfileControl=Off MaxRequestThreads=16

and restarted our server that is running the distribution service only.

I'll let you know tomorrow if this has sorted our problem.

Thanks

Mark

Thank you for continuing to let us know your progress. We also made the same change a few days ago and haven't had a single errror since. Seems that this resolved our problem as well.
