WDSC dropping connection

["Smith, Mike" <Mike_Smith@xxxxxxxxxxxxxxxx>]

I think this is the right forum, because I don't believe the issue is
with WDSC itself, but tell me if I need to post in the WDSC forum. 

I have 2 connections 1 to a production machine and 1 to a development
machine.  If I connect using my profile on production and for example
open a file on the IFS.  I can continue to open the file even an hour or
2 later.  However, If I do the same thing on my development machine,
after about an hour I receive a TCP connection dropped message if I try
to open the file again.  This happens with editing source also.  

I have tried comparing system values specifically QINACTITV(60) and
QINACTMSQ(points to a specific message queue)  and they are the same on
both machines.  It seems like it might be a system value issue, but I
don't see anything that stands out to me as the culprit.  

Anybody have an idea what will cause this?

Thanks
