Erm. I heard the system was in a very unhappy state and couldn't be logged into. After it was rebooted, the problem appears to have gone away. That is quite unsatisfying. "anole" runs on the same host, and occasionally fails to launch any parallel workers, and it seems to be pretty unhappy too -- very long runtimes (minutes where my smaller machines take seconds). So the machine may be massively overloaded and swapping or something like that, something to be looked into, but that doesn't explain how we get to a segfault without an underlying hard to reach bug in our code... -- Thomas Munro https://enterprisedb.com
