[Tinyos-help] JVM crashes running SerialForwarder on Linux

[Tony Mancill]

Dear TinyOS list:

Has anyone else run into a problem with the JVM crashing while running
T1's SerialForwarder?  What's odd is that it doesn't always happen
immediately.  In fact, sometimes the system will run fine for long
periods of time (I'm runing TestDrain and DrainBase on the motes), and
then wham, the JVM will die.  Other times it does right away.  I've
observed with both Sun and IBM's JVM.

$ java net.tinyos.sf.SerialForwarder
Java TOSSerial finalize
#
# An unexpected error has been detected by HotSpot Virtual Machine:
#
#  SIGSEGV (0xb) at pc=0xb12508f8, pid=5130, tid=2990263216
#
# Java VM: Java HotSpot(TM) Client VM (1.5.0_10-b03 mixed mode, sharing)
# Problematic frame:
# C  [libTOSComm.so+0x88f8]
Java_net_tinyos_comm_TOSCommJNI_NativeSerial_1close+0x48
#
# An error report file with more information is saved as hs_err_pid5130.log

Any ideas?

Thanks,
