Re: [Duplicity-talk] OSError: [Errno 24] Too many open files

[Kenneth Loafman]

Only half of this bug is fixed but that part is still useful.  The gpg
tasks now go away immediately and free up half (3) file descriptors that
they once held.  There is a patch attached to the bug report at:
https://savannah.nongnu.org/bugs/?21792 which applies to
GnuPGInterface.py in the duplicity module.

The other half of the fix will come with 0.6.0, checkpoint/restart.

I'll have this half out in 0.5.18 if you don't want to patch, probably
first part of next week.

...Thanks,
...Ken
