I updated the AWS Ubuntu 12.04LTS HPCC AMIs to 4.2.0-2 – the build went fine and I proceeded to initialize a 2x2 cluster to test; however, an envgen segfault (appears to be related to our libdeployutils) kills the cluster initialization.
/var/log/syslog:Dec 16 14:36:50 ip-10-232-159-77 kernel: [5739830.968953] envgen: segfault at 8 ip 00007f66c2983333 sp 00007fffeef3da10 error 4 in libdeployutils.so[7f66c296c000+41000]
I ssh-ed to the box and tried manually and core dumped:
