Created attachment 281949 [details] pax.log Attached also pax.log because at same time there is an issue.
(In reply to comment #1) > Created attachment 281949 [details] > pax.log > > Attached also pax.log because at same time there is an issue. Ago, did you try to resetting any pax flags on /usr/bin/akonadi_agent_launcher to see if helps?
(In reply to comment #2) > Ago, did you try to resetting any pax flags on /usr/bin/akonadi_agent_launcher > to see if helps? Atm I've dropped -M, and i don't see anything in pax/grsec.log
I've reproduced it also with -M, Now I'm resetting all pax flags
Finally, with all flags dropped: devil ago # paxctl -v /usr/bin/akonadi_agent_launcher PaX control v0.5 Copyright 2004,2005,2006,2007 PaX Team <pageexec@freemail.hu> - PaX flags: -p-s-m-x-e-r [/usr/bin/akonadi_agent_launcher] PAGEEXEC is disabled SEGMEXEC is disabled MPROTECT is disabled RANDEXEC is disabled EMUTRAMP is disabled RANDMMAP is disabled I see always segfault in grsec.log, but nothing in pax.log.
Is this still happening with 1.6.2?
atm I didn't see any warning(s)/error(s)
(In reply to comment #7) > atm I didn't see any warning(s)/error(s) OK cool. 1.6.0 is gone, so this should be fixed.
