2325830 - IQ could start with -tl 0 while default is 2 mins - SAP IQ16 SP10.x

Symptom

By default, the liveness time out is 2 mins for IQ to check for client connection liveness every 2 mins.

On IQ16 SP10.x, IQ starts without liveness time out check: -tl 0.
Thus dead connections could be still considered as alive and still listed in sp_iqconnection until IQ shutdown.

This could cause "Max connections exceeded" error and new conenctions wouldn't be able to be established.
