Does anybody see in db logs the "multi-threaded" ABL sessions after receiving the signals? For example, after receiving HANGUP signal? Try: grep " T-2 " *.lg T-2 I ABL 1923: (562) HANGUP signal received. I saw the same issue for other signals: Received signal 7; handling as SIGHUP. (4375) KILL signal received. (298) but these signals are rarely used. The statistics comparing the number of “HANGUP signal received” issued by T-2 to their total numbers from the customer running HP-UX: 2018/05/31 10:37:45 24 of 3388 (0.7%) 2018/04/20 18:47:41 308 of 2016 (15.2%) 2017/04/25 11:43:03 14 of 2509 (0.7%) 2017/04/20 11:50:05 24 of 2653 (0.9%) 2016/03/02 18:02:00 780 of 8012 (9.7%) It was not the full day logs – just the db logs until the incidents. That is why the percentage of the fake threads is varied between logs. Most of fake threads took place in the middle of day. It looks like there are the hundreds of “T-2” per day. Only 5 of them for last two years resulted in the critical issues for a database. Does it happen only on HP-UX?
