Unexplained Server Restart

bnichol — Mon, 26 Jan 2026 18:19:17 GMT

Is there a log to identify why a QVS would restart on its own?

I'm able to identify that a restart occurred in the Performance and Events log, but there isn't any indication why the restart occurred. Is there another way to identify the reason for this activity?

Here are outakes from the logs...

Those are the two logs that have the information you need. You could try setting the log level to high, but it looks like you already have that set. You could also try to correlate events in the Windows event logs. This application is good for that: http://community.qlik.com/qlikviews/1029

You working set size is 90 - 98%. Why so high? Default is 70 - 90% I think. Based on the perf log it looks like you're getting close to that RAM limit. This shouldn't cause a server crash, but sometimes it does.

Did you really have no server traffic between 02:36:00 and 14:52:00? Or are those just snippets from the logs? Sometimes when the server crashes, it stops logging to the log file.

I would call QlikTech Support.

The times 02:36:00 and 14:52:00 are the server start times, not the transaction times. There was the usual amount of activity between these times.

The working set is configured to reduce the amount of unnecessary Virtual Memory logging. The server usually runs about 80%-90%, and we only want warnings when those values are exceeded.

The event viewer had the following, but it is not helpful...

The QlikView Server service terminated unexpectedly. It has done this 1 time(s). The following corrective action will be taken in 10 milliseconds: Restart the service.

Any other suggestions?

By any chance you have same license installed on the network? May be on a test machine or something? If you do, QlikView services will restart every 10 minutes, I think.

Interesting fact, but this is the only instance using that license. If it was restarting every 10 minutes, I would be contacting my support contact.

Thanks,
