My node has currently spawned 1000 threads and the web interface isn't
accessible.. Hitting ctrl-break gave me (a frigging lot of callstacks and) a
'Found 1 deadlock' message, maybe this is the same issue:
"VM Thread" prio=5 tid=0x00a236d0 nid=0x24b4 runnable
"VM Periodic Task Thread" prio=10 tid=0x00a24898 nid=0x23f4 waiting on
condition
"Suspend Checker Thread" prio=10 tid=0x0003d590 nid=0x279c runnable
Found one Java-level deadlock:
=============================
"QThread-1473":
waiting to lock monitor 0x0361054c (object 0x184ff708, a
java.lang.Object),
which is held by "QThread-1463"
"QThread-1463":
waiting to lock monitor 0x02e3f4b4 (object 0x126ebdc8, a
freenet.PeerHandler),
which is held by "QThread-1473"
