Is it possible that the VM got stuck ? It did indeed. The machine only has 4GB of memory and 2GB swap. With make -j4 there are 4 processes each taking ~1GB and it is just swapping: 926 root 20 0 0 0 0 R 97.6 0.0 135:41.18 kswapd0 15794 buildbot 20 0 1539436 928056 0 D 2.4 24.5 1:41.92 cc1plus 15817 buildbot 20 0 781108 674280 328 D 2.4 17.8 1:08.31 cc1plus 15792 buildbot 20 0 1250264 763912 384 D 2.1 20.2 1:40.62 cc1plus 15800 buildbot 20 0 1427104 784820 132 D 2.1 20.7 1:41.67 cc1plus I'll reconfigure with make -j3 to see if that helps. I don't know why we are suddenly seeing this, did the code get that much bigger recently? Cheers, Mark
