What is a 'Type T' error?

[arvid_m-a]

We have a strange problem on our Qlik Sense server. What seems to have triggered it is changing the log configuration for the Qlik Engine.

We reduced the logging down to warning on all settings, and then the Engine would just shutdown and coredump everytime it was restarted. We increased the logging to debug to get some more hints, and the error went away... We turned the logging down to info, and now it is back to crashing.

The errors are as follows.

Start_Engine log file:

Thank you!  This was a huge help!  I just had this same issue due to changing the log levels.  The app logs get huge and the server was filling up.  I'll have to see if this issue was fixed in a later release.
