Disable “unaligned access to …” message when running java on Itanium 64








Installed Java 6 on Itanium 64 Altix 3000 system. But it gives

java(84473): unaligned access to 0x2000000001aee211, ip=0x2000000001cb9ef0
java(84473): unaligned access to 0x2000000001aee219, ip=0x2000000001cb9ef1
java(84473): unaligned access to 0x2000000001aee211, ip=0x2000000001cb9ef0
java(84473): unaligned access to 0x2000000001aee219, ip=0x2000000001cb9ef1
java(84473): unaligned access to 0x2000000001aee211, ip=0x2000000001cb9ef0

when running a java application.

You can actually disable the messages:



Prepend


prctl --unaligned=silent 



to java command line will disable the messages.
