XS engine hangs out on "network read"

Hi,

I've developped a sap ui5 project on top of xs engine in order to browse our data.

Everything working fine on HANA SP7.

But sometimes, when i'm trying to get data with xs js script or when i'm refreshing the model, the xs engine server hangs out.

In the Performance tab in hana studio, i can see that the current thread is blocked with the status "Network Read"

Have you heard about this issue ?

Can it be fixed ?

Regards
