Process system tasks are + for example utilized when purging code, garbage + collecting literal data, and when issuing an ordinary + garbage collection from another process. + + The bug does not trigger frequently. Multiple code + purges in direct sequence makes it more likely that + this bug is triggered. In the cases observed, this has + resulted in a hanging code purge operation. + + + OTP-16640 Application(s): erts + Related Id(s): OTP-16193 + + A literal area could prematurely be released before all + uses of it had been removed. This occurred either when + a terminating process had a complex exit reason + referring to a literal that concurrently was removed, + or when a terminating process continued executing a + dirty NIF accessing a literal (via the heap) that + concurrently was removed. + + + OTP-16641 Application(s): erts + + The VM could potentially crash when checking process + code of a process that terminated while executing a + dirty NIF.
