BETA SERVER 1.7.0.5157 (updated BETA 1.07) I am regularly checking my "arma_server.RPT" file to scan for coding and generic errors. I managed to get rid of all current script errors but my Mega-Coop-Dynamic War mission suffers from Async issues; meaning that after playing for about 20-30min it can happen to any player that he gets killed by invisble enemies / he doesn't see any enemies anymore / he cannot kill any enemies. So I assigned markers to enemy units to trace them. After a while I basically saw a marker walking by right in front of me but I couldn't see any man or vehicle there. Next thing was that I got shot (just fell, didn't see or hear anything). Since I am testing these things on a dedicated server in my local LAN first I would exclude bandwidth issues (100mbit local). I have studied the included "DS-Admin.rtf" which talks about optimizing performance. There it says to tune paramters in the "Flashpoint.cfg" file. Well, since we rather talk about the Arma.cfg file I added the following lines to the Arma.cfg as well as to the server specific "sample.cfg" file: <table border="0" align="center" width="95%" cellpadding="0" cellspacing="0"><tr><td>Code Sample </td></tr><tr><td id="CODE"> MaxMsgSend = 256; MinBandwidth = 512000; MaxBandwidth = 768000; MaxSizeNonguaranteed = 4096; And still my arma_server.RPT records hundreds of lines with the identical text: <table border="0" align="center" width="95%" cellpadding="0" cellspacing="0"><tr><td>Code Sample </td></tr><tr><td id="CODE"> NetServer: trying to send too large non-guaranteed message (3291 bytes long) Message not sent - error 0, message ID = ffffffff, to 1884877695 (Victor) The "non-guaranteed message" size varies between 3000 - 3800 bytes. Can anybody recommend a better setting? Seems like setting these variables didn't make any difference at all - same errors before (using default) and afterwards. This causes Async issues all over the place. Positions not being updated, people not getting in or out of vehicles, the invisible death, player's head getting stuck in free-look mode etcpp. So I just did a "monitor" on the server and it shows "Outgoing: 2422kbps, Incoming 181kbps" on average. Isn't that a bit much for a simple mission with a few trucks, 2 - 3 tanks, 4 Helos and about 120 soldiers? I remember we played this mission often w/o any problems lately. This started very recently all of a sudden (maybe after updating to 1.07b-b?). Puzzled, Victor
