Memory exhaustion on buildsys?

[Richard Shaw]

I'm trying to build OCE for EL-6 and it has failed twice. Looking at
the error it doesn't give any details:

[100%] Building CXX object

The job log shows and issue but it looks like it happens prior to building:

State Changed: setup
error: db3 error(12) from dbenv->open: Cannot allocate memory
error: db3 error(12) from dbenv->close: Cannot allocate memory

Config(el-6-x86_64-rpmfusion_nonfree) 29 minutes 9 seconds
--- end ---

It builds fine on a local mock build...

Any idea what's going on?

Thanks,
Richard
