QDS gets disconnected frequently

[Rema_04]

The QDS service on the prod server gets disconnected frequently with below error:

A timeout (30000 milliseconds) was reached while waiting for a transaction response from the QlikViewDistributionService service.

Can anyone help here

Hello,

1. You can adjust the communication timeout between the QMS and QDS server per below link.

2. How busy is your QDS server , does the issue happen when it's under high usage . (meaning reload) .

3. Confirm there aren't any network delay between the servers (if multinode) .

3.Confirm there aren't any network delay between the servers (if multinode) ->No, there is no network delay on the platform

In general are the various default-configurations to timeouts and similar settings well chosen to ensure performance and stability. Therefore adjustments to them may make the matter even more worse and should be rather not the first measurement.

Before adjusting the working sets and/or the number of available cores and/or the number of max. possible concurrent tasks and/or changing any timeouts and/or moving the tasks into another order/dependency/time-slot or similar measures it would be useful to monitor the happenings on the server with the various log-files from QlikView and the OS - maybe starting with the governance dashboard.

Hi @Rema_04,

Have you reviewed the QMS log? Can you upload it here?
