Problems with OFS V3.3 and Ethway V1.3 driver

Goals and Symptoms:

OFS V3.3 Ethway V1.3. TSX107V5
Testing with our client delivered with OFS :
if we create 1 item %W0 and another one %W1 it works well but if we create a third item %W100 then error "NO FREE SOCKET" appears . Our conclusion is that the error appears when OFS needs to send more than 1 ethway requet ("Net Request" variable > 1). We have tried modifiyng max channel parameter but if you set more than 1 channel , PC crashes.

Causes and Fixes:

The system works well:
- We have installed Driver Ethway V1.4 (with 1.3 version PC crashes when more than 1 Item was created.
- We have divided the items in several groups.
