Issue after changing simultaneous qv engine from 6 to 8

[Anonymous]

We have recently change the number of qlikview engines from 6 to 8  on qlikview server . After that few documents fails throwing below error. Observed that this happens when the engine 7 or 8 is attempted to be used.

Any suggestions?

Hi

We had a an issue like this giving that error we solved it by restarting the Qlikview Distribution service on the publisher server
