The ulimit approach is way too cumbersome. The pam_limits solution is not well-documented on my Debian system, which doesn't even have a man page for /etc/security/limits.conf, though the file has comments, now that I know where to look. PAM is powerful and flexible, but "easy to use" is not a phrase that comes readily to mind. :-) The PAM approach would probably be workable for special-purpose audio distributions like Planet CCRMA or DeMuDi. That still leaves all the audio developers with a significant challenge trying to explain every configuration step to all our other users. AFAICT, PAM configuration is rather distribution-specific, so that could become a significant burden. It appears that a limits.conf line like this might work... @audio - memlock 10000 # is there any way to say "unlimited"? I'll experiment tomorrow to see if I can actually make this work. -- joq - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ | ||||||||||
