Access1 is a library of timely technical information for the Sun
developer community. Users have free access to TechNotes, white papers
and the Access1 patch database, which covers product installation,
security issues and driver updates. Developer Support contract
customers are able to log and query support calls via email and receive
special access to post-installation patches, bug reports and technical
bulletins written by Sun technical engineers.
One of the recent items on the Access1 Web page concerns how
segmentation fault occurs with JavaTM virtual machine (JVMTM) for
When running JavaTM technology applications under certain Linux
installations/configurations, the JVM for Linux
crashes with segmentation faults under a heavy load.
There is some information in the README file of the JavaTM 2
Platform, Standard Edition (J2SETM) Software Development Kit package
that specifies changes that should be made to the Linux configuration
that will limit the system resources available to the current shell and
its descendants. However, this does not change the situation with the
One of the most likely root causes for the JVM exiting with
segmentation faults is a problem with specific versions of the Linux
glibc library and the JVM for Linux. It has been discovered that the
combination of glibc v2.2.2 and the JVM for Linux is not stable and
causes the JVM to crash. Upgrading the glibc to a newer version such as
glibc 2.2.4 will ensure that the JVM does not exit with segmentation
faults under a heavy load.
The Tech Notes for February 2002 offer technical details on this and
other problems and solutions.
Support Readiness Documents (SRDs) are educational documents created
specifically for Developer Support Engineers. They have now been made
available for the developer community and are available for free
download in either Postscript or PDF format. Primarily for Java
technology products, these SRDs focus on issues immediately relevant to
support, such as installation, configuration and common user problems.
New documents include:
- JavaTM Web Start 1.0
- JiroTM Technology 1.5
There are more documents for J2SE, JavaTM 2 Platform, Enterprise
Edition (J2EETM) and ForteTM Tools.
