Since the following bug

  4975660 SA-JDI: SAPIDAttachingConnector.attach() causes debugger VM crash on
Linux

was fixed in Tiger-b38 SA-JDI connectors do not crash on Linux.

However, SAPIDAttachingConnector still fail on Linux intermittently.
Sometimes it throws IOException with no description.
I noticed this failure often on Redhat AS 2.1 and never on Redhat Linux 9.0.

To reproduce the failure:
  cd /net/jano.sfbay/export/disk20/GammaBase/Bugs/<this bug number>
  sh build.sh $JAVA_HOME
  sh run.sh [-g] [-v] $JAVA_HOME [JAVA_OPTS]
where
    -g - run test with java_g binaries
    -v - run test in verbose mode

Here is test output:
