jvm crash - jlong_disjoint_arraycopy

  when we are accessing some io resources,like writing to disk,there may be a java jvm crash by below:

 

#
# A fatal error has been detected by the Java Runtime Environment:
#
#  SIGBUS (0x7) at pc=0x00007f9a785c2690, pid=1150, tid=140300276668160
#
# JRE version: 6.0_31-b04
# Java VM: Java HotSpot(TM) 64-Bit Server VM (20.6-b01 mixed mode linux-amd64 compressed oops)
# Problematic frame:
# v  ~StubRoutines::jlong_disjoint_arraycopy
#
# If you would like to submit a bug report, please visit:

  in general this is eplicitly,its disk related fault.so u will have some ideas if having a check on it:

 

sudo hdparm -t /dev/sda

Timing buffered disk reads: 356 MB in  3.02 seconds = 117.85 MB/sec

  this result shows that the read speed of this device is slow,of course ,u can comparse it with other nodes for a confirm.for some more details ,u can go forward to [1]

What does intermittent “Input/output error” suggest?

How do I find on which physical device a folder is located?
