Thanks for this feedback, it looks very thorough. I'll work through your suggestions later on this week or at the weekend.</div>

So that I can get a better handle on what's causing the issue, am I right in saying that each instantiation of an abstraction constitutes one file descriptor?</div>

this is not really a problem with pd, but with your shell- or system<br>
configuration limiting the number of open file descriptors.<br>
<br>
check your current shell-limit with<br>
ulimit -Sn<br>
-S is for soft limit (you can lower, but not raise, the hard limit).<br>
raise the limit in your shell with<br>
ulimit -n 65536<br>
start pd from that shell and see if the situation improves.<br>
<br>
if that doesn't help, you can check the kernel limits with<br>
cat /proc/sys/fs/file-nr<br>
which returns 3 numbers, the first of which is the number of open files,<br>
the last of which is the limit.<br>
<br>
increase the value of "nofile" in /etc/security/limits.conf<br>
do<br>
sudo sysctl -p<br>
<br>
additional steps are required to make these settings permanent, the<br>
ulimit -n 65536 would have to go into your .bashrc so it's executed at<br>
system startup. if you normally start pd from your GUI you'd have to<br>
restart your system (actually just xorg) so your master shell knows<br>
about the new value. there's other ways, one of which would be to start<br>
pd from a wrapper script, or probably gnome provides that sort of<br>
environmental setup for it's program shortcuts.<br>
<br>
there's more information<br>
