are there any eclipse tools for detecting deadlock situations? i have a
small deamon type application that processes orders from a database and
sends request xml and gets response xml from a socket. it locks up
infrequently and very randomly. i've eyed the code and don't really see
where it might be locking as i don't see any waits or notifys and the only
thing that could be common between threads is the socket/port
communication being used.

i saw that feature, and unfortunately, i don't think i have much control
over the vm that's being used. also, this feature only works when you can
use ctrl+/ or some keyboard strokes on the application when it locks up.
my appllication is a daemon type program which is managed by init on unix.
thus, i don't have keyboard access to abort the program when it locks.
the best i've thought of is if i can run it in debug mode and connect when
there's a deaklock then perhaps i can see what's being locked if anything.
if anyone else has any suggestions for good places of info, it would be
most appreciated.
