We had noticed, that Foxweb could hang an NT server in case of insufficient disk space on drive where Foxpro channels create temporary files and "restart channels" setting of FoxWeb is set.
An error occurs in channel (for example after lengthy SQL SELECT) and Foxweb tries to create a new channel which also produce an error, then another and another until server stops responding.
We were using Foxweb 2.1 and VFP7.
