J2SE Version (please include all output from java -version flag):
  java version "1.5.0-beta"
  Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0-beta-b32)
  Java HotSpot(TM) Client VM (build 1.5.0-beta-b32, mixed mode)

Does this problem occur on J2SE 1.3, 1.4 or 1.4.1? Yes / No (pick one)
  No.

Operating System Configuration Information (be specific):
  RH Linux 9 + updates
  RH Linux 7.1 + updates
  Other Linux distributions (reported by customer, unverified)


Bug Description:
  VM crash with large heap sizes on Linux, but it works fine if
  -Xshare:off is supplied with the VM startup options or if reduce the
  maximum heap size parameter (-Xmx) to 256m while even 384m maximum
  heap size causes a failure. it could be reproduced on different
  with Debian GNU/Linux unstable as well (log file attached).

  The RH7.1/RH9 machines both run clean RPM installs of kernel, glibc,
  etc. No custom kernel, no patches, no custom compiled libraries. Just
  all RedHat updates.

  One observation which might or might not be important: All kernels where
  this occurs have highmem enabled (CONFIG_HIGHMEM4G=y). This seems to be
  the default for the latest RH kernels.
