Marking as fixed in Eoan, since it already has systemd v242. ** Also affects: systemd (Ubuntu Disco) Importance: Undecided Status: New ** Changed in: systemd (Ubuntu) Status: Incomplete => Fix Released -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1840435 Title: Systemd >=240 sets a clamp of 64MB for RLIMIT_MEMLOCK, too low for some applications.

[Bug 1840435] Re: Systemd >=240 sets a clamp of 64MB for RLIMIT_MEMLOCK, too low for some applications.
Upon further inspection, this is actually fixed in systemd 241. To reproduce, try setting a LimitMEMLOCK higher than 64mb for the system unit user@.service, OR for any unit executed by a systemd --user process. You will see that the RLIMIT_MEMLOCK is actually clamped to 64MB. This can be observed by using prlimit -p <>. You can reproduce by trying to give a user session (via user@.service OR /etc/systemd/user.conf) a LimitMEMLOCK of greater than 64MB and then inside a systemd unit or inside a gnome-terminal (since gnome terminals in at least disco and newer are run under a systemd user-service) try to execute `jackd -d hw:0 -r 48000 -p 256 -n 3 -S`. You may need to suspend/stop pulseadio. On my system at least (USB audio only), jackd wants to memlock 82280346 bytes (82MBish) of RAM for audio buffers and the like. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1840435 Title: Systemd >=240 sets a clamp of 64MB for RLIMIT_MEMLOCK, too low for some applications.
