Hi -
I'm investigating recurring server crashes on our CF MX 7
server and have noticed in the Hot Spot process dump a HUGE number
(in the hundreds) of obj-skimmer daemons, all marked
[_thread_blocked].
What kinds of things might cause this to occur?
Start of a typical dump:
#
# An unexpected error has been detected by HotSpot Virtual
Machine:
#
# Internal Error (4A41564123414C4C530E4350500016), pid=4928,
tid=6872
#
# Java VM: Java HotSpot(TM) Server VM (1.4.2_11-b06 mixed
mode)
