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

[Edward Jiang]

Hi Zhang,

I don't think duplicity itself would open many files, were you running some other processes at the same time?

Try

ulimit -a 

to see the open files limit, normally it should be 1024, which is normally enough.

ulimit -n [NUMBER]

to change that, or edit /etc/security/limits.conf (should be this file, can't remember off hand)

I hope this solves your problem.

Regards
Edward
