Description David Bennett 2006-02-17 20:18:08 UTC 
Description of problem:

On a Tomcat web application running on the IBM JVM, the JVM crashes with 
SIGSEGV occasionally when an Exception is thrown by a Servlet or JSP for to 
the application server for processing.  

Dump file reports:

1HPSIGRECV     SIGSEGV received in ?? at 0xffffffff in ??. Processing 
terminated.
1HPFULLVERSION J2RE 1.4.2 IBM build cxia32142-20050609

It appears as though the instruction pointer (EIP) is being corrupted:

Version-Release number of selected component (if applicable):

  IBM JVM cxia32142-20050609 
  java-1.4.2-ibm-devel-1.4.2.2-1jpp_9rh

How reproducible:

This has occured when processing a NullPointerException and also an 
IOException due to a directory permission problem.

Other environments running the same application under heavier load do not 
exhibit the problem.

  See javacores attached.

Gzipped java core from IOException throwing Signal 11 

This Signal 11 occured during normal processing of an IOException.  The
exception was a permission issue regarding a file write, However,  the Tomcat
applications error handler defined in WEB-INF/web.xml was not called.  Instead
this strange Signal 11 occured.
Comment 8 Thomas Fitzsimmons 2006-11-24 19:12:09 UTC 
Mark, has IBM seen this problem before?  Do you know if it has been fixed in the
1.4.2 SR6 release?
