<TITLE>New Node Assitance Please - Inbound audio & video freezes</TITLE>
</HEAD>
<BODY>
<P><FONT SIZE=2>I am trying to isolate a problem that occured yesterday during Open Testing where our inbound audio & video would periodically freeze (approx ever 5 minutes). This is a new node and -- any assistance/advice would be appreciated...</FONT></P>
<P><FONT SIZE=2>CPU & memory looks good on all machines as far as I can tell (TOP & Task Manager). The only error messages I see are on the Video Capture machine:</FONT></P>
<P><FONT SIZE=2>vic: Unregister caught error can't unset "ag_slot_allocated (-0159)": no such variable</FONT>
<BR><FONT SIZE=2>vic: Source was zz@xxx.xxx.xxx.xxx</FONT>
</P>
<P><FONT SIZE=2>This occurs numerous times with the Source info and "ag_slot_allocated" number varying.</FONT>
</P>
<P><FONT SIZE=2>Following are the node specs:</FONT>
</P>
<P><FONT SIZE=2>Audio:</FONT>
<BR><FONT SIZE=2> 2.4GHz P4,</FONT>
<BR><FONT SIZE=2> 512MB RAM,</FONT>
<BR><FONT SIZE=2> SoundBlaster PCI128,</FONT>

<BR><FONT SIZE=2> AG software is the snap-006 release applied via update script,</FONT>

<P><FONT SIZE=2>Video:</FONT>

<BR><FONT SIZE=2> Dual PIII 1.5GHz,</FONT>
<BR><FONT SIZE=2> 1GB RAM,</FONT>
<BR><FONT SIZE=2> Matrox G200 (hoping to eventually get a PC that can also handle an AGP card),</FONT>
<BR><FONT SIZE=2> Win2k with lastest Critical Fixes & ServicePacks,</FONT>

</P>
<P><FONT SIZE=2>...all on an Intel 410T Switch for the network connection.</FONT>
</P>
<P><FONT SIZE=2>Time is synced on all machines.</FONT>
</P>
<P><FONT SIZE=2>Symptoms are:</FONT>
<BR><FONT SIZE=2>On Display machine - remote video freezes, local video continues working</FONT>
<BR><FONT SIZE=2>On Audio machine - received audio streams in RAT disappear from display</FONT>
<BR><FONT SIZE=2>Eventully audio and video will just start working again.</FONT>
<BR><FONT SIZE=2>Mary indicated that our outbound streams to other nodes was not interrupted - and there were no voiced complaints on RX quality or our streams.</FONT></P>
<BR>
<P><FONT SIZE=2>FWIW... I have been lurking in the test room since 11am this morning without any interruption in the video streams. Haven't done anything with audio yet though. </FONT></P>
<P><FONT SIZE=2>I'll be here most the afternoon if anyone could stop by for a few minutes to assist in troubleshooting. I've contacted our network folks who are standing by in case it happens again...</FONT></P>
<P><FONT SIZE=2>Thanks</FONT>
