gc/gctests/MemoryEaterMT instability crashes with SIGSEGV with 6.0 fcs, u1, u2, u3. This happens only on Solaris 10 U2 (with all recommended patches installed) sun4v arch (aka niagara). The test passes with Solaris 10 U3 sun4v and other Sparc Solaris configurations like sun4u.

Test fail:

  Solaris 10 6/06 s10s_u2wos_09a SPARC

# Problematic frame:
# J sun.nio.cs.StreamEncoder.implWrite([CII)V

JAVA_OPTS="-client -Xmixed -DHANGINGJAVA17998 -Xbatch -XX:CompileThreshold=2 -XX:+UseParallelGC"

How to reproduce:

1. logon to stt-32.russia
2. cd
/net/vice/export/home0/results/6u2/02-week1/vm/vm/SOLARIS-SPARC/client/vm-vm_6-ur_client_SOLARIS-SPARC2007-07-11-20-58-46/ResultDir/MemoryEaterMT
3. ./rerun.sh (6u3b01)

rerun_jdk6u1.sh
rerun_jdk6u2.sh
rerun_jdk6fcs.sh

The failure is somewhat hard to reproduce. It does not happen every time.
