Some time ago I sucessfully ran v1.1.5 dedicated servers and even before that I ran a soldat server (some early versions). It was working ok all the time; but now it just crashes after some time. Application just hangs. No error messages or anything of the sort. Maybe it is related to priority changes? (I set priority higher than normal to minimise lag) Or is it that I run 2 dedicated servers and a client at the same time? Anyway - fromk all 3 apps running only one server crashed - the one people were actually playing in.
Any help apriciated.

Intrestingly there were no crashes for some time now, but there is still another issue - terrible LAG. I don't know from where it arises, but I also experience this lag - although I connect to 127.0.0.1 (I'm convinced this is NOT connection problem). The nature of the lag... sometimes everything is ok, then a moment later its stuttering almost to a halt.

er, are you talking about still running 1.1.5 servers, or are you talking about issues with 1.3?
