Hi,
Got an app that coredumps and the app developer is blaming the O/S install as
the problem. This is the truss output (last part shown):
shmdt(0xFF120000) = 0
stat64("/bto/sys/wmc4.1.7", 0xFFBFD998) = 0
shmget(1358958591, 0, 0644) = 8
shmat(8, 0, 0) = 0xFF120000
stat("/platform/SUNW,Ultra-Enterprise/lib/libc_psr.so.1", 0xFFBFC748) = 0
resolvepath("/platform/SUNW,Ultra-Enterprise/lib/libc_psr.so.1",
"/platform/sun4u/lib/libc_psr.so.1", 1023) = 33

mmap(0xFF0D8000, 13512, PROT_READ|PROT_EXEC, MAP_PRIVATE|MAP_FIXED|MAP_TEXT, 3,
0) = 0xFF0D8000
mmap(0x00000000, 8192, PROT_READ|PROT_WRITE|PROT_EXEC, MAP_PRIVATE|MAP_ANON,
-1, 0) = 0xFF0C0000
close(3) = 0
munmap(0xFF0D0000, 8192) = 0
stat("/proc/06139", 0xFFBFDAF4) = 0
shmdt(0xFF120000) = 0
Incurred fault #6, FLTBOUNDS %pc = 0x0001C88C
siginfo: SIGSEGV SEGV_MAPERR addr=0xFF2707B0
Received signal #11, SIGSEGV [default]
siginfo: SIGSEGV SEGV_MAPERR addr=0xFF2707B0
This is the pstack output:

m0072057_wmc:
Can anyone here tell me if these outputs contain any hints as to what might be
the problem? This is Solaris 10 and the main difference between our server and
the application developers is the level of the kernel patches (ours is later
than theirs).
