fatal error: unexpected signal during runtime execution

[rif]

I have this fata error in my project: there is a large amount of data (the process takes around 4gb in memory) cached in a map in the running process.

The steps I reproduce the error are these:

• load the data in the map
• the memory of the whole process gets to around 6gb
• leave the process for a while and the memory drops to around 4gb
• trigger another load of the whole data

The issue appears on a Debian7 using go version go1.5.1 linux/amd64
Linux CgrTest2 3.2.0-4-amd64 #1 SMP Debian 3.2.68-1+deb7u3 x86_64 GNU/Linux

I got this issue both on a virtual machine and a real hardware both running Debian7 amd64.

The whole stack trace:

Thanks. This is a dup of #13227.
