I use Jboss Profiler 1.0 RC3 with -JBoss 4.0.2, -JD1.4.2 -Solaris 9 JVM for Jboss is running with -server. On 8 of 10 tries to capture data (e.g. kill -3) JVM crashes with a core dump. Here is the console output Full thread dump Java HotSpot(TM) Server VM (1.4.2_05-b04 mixed mode): "UIL2(SocketManager.MsgPool@1bfdaa4 client=172.16.10.151:2900)#2" daemon prio=5 tid=0x02416d10 nid=0x5a in Object.wait() [717ff000..717ffc28] at java.lang.Object.wait(Native Method) - waiting on <0x7b40c470> (a ....
