SIGUSR1 is used for all sorts of internal cross-process signaling purposes. There's no need to hypothesize any external force sending it; if somebody had broken a PG process's signal handling setup for SIGUSR1, a crash of this sort could be expected in short order. But having said that, are we sure 10 is SIGUSR1 on the OP's platform? AFAIK, that signal number is not at all compatible across different flavors of Unix. (I see SIGUSR1 is 30 on OS X for instance.) > Are you running any procedural languages other than PL/PgSQL, or any > custom C extensions?
