I > don't really have better ideas :/ Turns out that right after sending this e-mail, I checked, and one of the build was stuck exactly in this situation. The process tree is like this: 23332 pts/5 S+ 0:01 | \_ python ../buildroot-test/scripts/autobuild-run -c autobuild-run.conf 23969 pts/5 S 0:00 | | \_ timeout 28800 make O=/ssd1/thomas/autobuild/instance-2/output -C instance-2/buildroot BR2_DL_DIR=/ssd1/thomas/autobuild/instance-2/dl BR2_JLEVE 23970 pts/5 T 0:19 | | \_ make O=/ssd1/thomas/autobuild/instance-2/output -C instance-2/buildroot BR2_DL_DIR=/ssd1/thomas/autobuild/instance-2/dl BR2_JLEVEL=4 10928 pts/5 Z 0:00 | | \_ [bash] So basically, the Buildroot "make" invocation only has one child process: a bash process that is defunct. This instance is really stuck in the ./bootstrap call: make[1]: Entering directory '/ssd1/thomas/autobuild/instance-2/output/build/host-erlang-rebar-2.5.1' ./bootstrap [nothing else] I tried running the exact make command that builds host-erlang-rebar in a terminal, inside the build directory of this build, and it worked perfectly fine. So even more puzzled. I see however that 'bootstrap' tries to play with the hg and git VCS to get a commit reference. Maybe this is failing for some reason? Any other idea?
