Siggghhhh... yet another segmentation fault

Okay, here’s ANOTHER segmentation fault error. I finally got a decent amount of locked memory available for regular users, but now when I try to open an existing session I get the usual stuff, but then it crashes with:

segmentation fault (core dump)

I didn’t have access to my Ardour computer when I did the above post, but I’m at it now and here’s the complete startup output:

gene@lemon:~$ ardour2
WARNING: Your system has a limit for maximum amount of locked memory!
This might cause Ardour to run out of memory before your system runs
out of memory. You can view the memory limit with ‘ulimit -l’, and it
is normally controlled by /etc/security/limits.conf

This is for a brand-new session; the only thing I did was create the session, close Ardour, and attempt to re-open it. I should have plenty of locked memory:

ulimit -l

@2handband: 4096 is still ridiculously small! this is in kilobytes. Ardour needs many megabytes. Your system no doubt has many gigabytes. You should use something like ulimit -l unlimited or at least ulimit -l 1073741824 (the latter is 1GB). If you don’t use unlimited, at least use about 75% of your physical RAM.

Oh, that’s kb?? Oops, don’t I feel like a jackass. I’ll get back to you shortly…

You, sir, are the man. I’ve just done half a dozen session re-opens, all successful. Thanks! Hopefully all of my future questions will be in the how-to section…
