JVM Crashes
Hi,
Sometimes the Tomcat's JVM is crashing:
#
# A fatal error has been detected by the Java Runtime Environment:
#
# SIGBUS (0x7) at pc=0x00002aaab7a8ad50, pid=21850, tid=1075628352
#
# JRE version: 6.0_38-b05
# Java VM: Java HotSpot(TM) 64-Bit Server VM (20.13-b02 mixed mode
linux-amd64 compressed oops)
# Problematic frame:
# C [libnio.so+0x4d50] Java_java_nio_MappedByteBuffer_load0+0x40
#
# If you would like to submit a bug report, please visit:
# http://java.sun.com/webapps/bugreport/crash.jsp
# The crash happened outside the Java Virtual Machine in native code.
# See problematic frame for where to report the bug.

This page (queries/virtual/filePDF) is accessed often, but occasionally it
happens. Any idea?
Thanks in advance.

Thanks, I'll analyze this issue.

I know, but I decided to post here because the level of users is very good.

A dynamically generated PDF?
I wonder whether you are stumbling upon unexpected closing of
outputstream, a known issue with ImageIO and some other libraries, see
http://wiki.apache.org/tomcat/FAQ/KnownIssues
The library where the crash occurs ("libnio.so") belongs to Java
Runtime, not Tomcat.
What is your exact version of Java and of Tomcat? What Connector
implementation are you using in Tomcat?

Konstantin Kolinko
