While doing testing, we noticed that erlang encountered memory corruption when the number of processors in sysfs was less than the configured value. Ben H. posted a fix to erlang at:

http://erlang.org/pipermail/erlang-patches/2012-March/002705.html

and it was eventually commited as

https://github.com/erlang/otp/commit/8c34a2dc70070cca8d97ad3c0f2dfbec1a0d82d8.

I am buliding a test erlang for internal use based upon erlang-R15B-0.1.fc17.src.rpm, but noticed that the spec file therein reference openjdk-1.6.0 and fc17 has openjdk-1.7.0. I changed my copy of the spec, but this probably also needs fixing in the srpm?
