systemd-229/230 crashes
Posted: Wed Jun 01, 2016 6:45 pm
I'm not sure whether some systemd crashes actually related to grsecurity or I'm just see more information because of the capabilities of grsec.
I have an unsuccessful upgrade from systemd-228-r1 to systemd-229 because of crashes. Now I'm experiencing crashes while tried to upgrade to systemd-230-r1.
After crash bruteforce logic is activated. System acts slowly. It was more serious by the time of -229, but it is still noticeable in case of -230-r1.
Some log messages I could capture related to the issue:
Any ideas on this problem persisting since systemd-229?
Thx: Dw.
