Thanks a lot

Is there a reproducable situation you can find that always causes the disconnect? For example, does it always disconnect after 10mins? Does it always disconnect after modifying the code 5x, things like that.

Unlucky there is no reproducable situation (or I do not find it) but the problem is more frequent to the begin of debug session.
I red in forum that other users reported the same problem in 5.0.1 version. I used for one year 4.x version and no one time reported thsi problem. Is it possible a combination of jdk 1.5_09 for this probelm ? I have Jrockit Jvm installed on my pc. Can I use this Jvm to know if the problem is jdk ? How can I configure Myeclipse to use JRockit jvm ?
Thanks a lot for all

Gandalf,
You can force MyEclipse to start with a different vm by using the -vm argument on the command line and point it directly at the executable like this:

eclipse.exe -vm C:\Program Files\Java\jdk1.4.2_12\bin\javaw.exe

or something along those lines. We don’t test with JRockit, so if that doesn’t work, you could try a recently build (100+) of JDK 6 (http://jdk6.dev.java.net) as we’ve seen some users say that actually fixed some issues for them, but again not a JDK we test with (in my personal experience JDK 6 was pretty good running MyEclipse, but I didn’t test it very hard).
