Yes, attempted has been made, but it's something difficult to diagnose, the machine becoming unresponsive. make seems to leave many processes hanging, causing extreme swapping, which doesn't work well on the Octeons which swap over NFS. It seems to work fine on the Octeons which swap over NFS. mips being one of the few architectures with a buggy version of make, I wonder if it's related to #890430 or #890309. I guess it's time to revert to the make version in testing, which would also greatly improve, or rather restore, the build time. > If it's memory exhaustion, are linux and other large packages being > blacklisted for these build hosts? In the meantime, I have blacklisted linux on the Octeons swapping over NFS. It should therefore build fine. Aurelien -- Aurelien Jarno GPG: 4096R/1DDD8C9B aurelien@aurel32.net http://www.aurel32.net
