Same problem here, when I reach 502 maps raise the following exception:

Traceback (most recent call last):
  File "/usr/lib/python2.7/site-packages/wx-3.0-gtk2/wx/_core.py",

OSError: [Errno 24] Too many open files

But checking the number of opened file on my system, it seems two order
lower than the maximum:

$ cat /proc/sys/fs/file-nr23422   0       1628292
$ cat /proc/sys/fs/file-max 1628292

I’ve attached also the complete log of the command in DEBUG mode, but I was
not able to understand where the problem could be. I’ve also rebooted just
to be sure that the system was fresh, but again after 502 maps it breaks
with the same error.

Any ideas?

Pietro
