An Unexpected Signal : 10 occurred at PC=0xFE55FC8C occurs when Merlin AWT reliability test runs on Solaris 8 (64bit) for build 69. But the same test runs successfully (without crash) on Windows for 36 hours. The test crashes at different points at different time leading to the following error.

The stack trace is:
