Is completely a question to sun. I suspect that it is a bug in the incremental gc.
May be you should upgrade to JVM 1.3.1_01 There two bugs fixed that might help you: (Don't know if this changes where between v1.3.1-b24 and 1.3.1_01) http://developer.java.sun.com/developer/bugParade/bugs/4469343.html (Might solve the problem) http://developer.java.sun.com/developer/bugParade/bugs/4450681.html (Might give better information what caused the signal) > -----Ursprüngliche Nachricht----- > Von: Yoav Shapira [mailto:[EMAIL PROTECTED]] > Gesendet: Donnerstag, 6.
