I’m trying to set up a real time environment using Linux rlimits with PAM on my Gentoo-box. When I run qjackctl I get these messages:
JACK: unable to mlock() port buffers: Cannot allocate memory JACK: unable to mlock() port buffers: Cannot allocate memory cannot use real-time scheduling (FIFO at priority 20) [for thread 1091053904, from thread 1091053904] (1: Operation not permitted) cannot lock down memory for RT thread (Cannot allocate memory)
What do they mean exactly? And what can I do about it?
