I've been having a strange problem with the R3 Xsun server recently. A program I've been working on has been provoking XIO error messages, either EPIPE or ECONNRESET. The problem seems to happen when the program is in the process of mapping a great many windows. Background data: the program is built on top of InterViews 2.4, and linked with the X11R2 library on the Butterfly GP1000, which is where it's being run. The display server is a Sun 3/50 running a vanilla X11R3 release and awm (from the original X11R3 release tape). The program works just fine when the same display server is running X11R2, so I think that rules out any network funniness between the Sun and the Butterfly. A somewhat similar program works fine with either version of the server, but it doesn't map anywhere near the number of windows the faulty program does. Has anyone else seen this happen? Is it a server bug? (Seems like it must be.) Or maybe a problem with awm? (Though the application shouldn't be doing anything with the window manager at the point things break.) ---Walter
