Websphere Development Studio dropping connection

When I use WDS at one of my clients, my session disconnects after an idle
period (not sure how long, maybe 30 minutes) and I have to close and restart
WDS to get reconnected. When I get reconnected and try to reopen the source
member that I had open it tells me the member is already open and gives me
an option to kill the old job. It is also worth mentioning that I do not
lose my 5250 connection when this happens so it is not a network dropping
issue.



When I am connected to my company's iSeries, I can leave WDS idle for hours
and I never lose the connection. Is there some kind of timeout on my
client's iSeries that is causing the disruption?
