[Csync2] I/O Error 'Too many open files'

[Yann Sarazin]

Hello,

I'm trying to use csync2 to synchronize about 1,300,000 files but I've 
got the following error :

<24924> ERROR: tmpfile() didn't return a valid file handle!
<24924> I/O Error 'Too many open files' while creating new data temp 
file in rsync-patch: /home/www/correzrt/correzrt_price_list_4734.pdf
<24924> ERROR: tmpfile() didn't return a valid file handle!

This error occur after a few minutes of successful synchronization, and 
after the error occurred the csync2 -ii process continue running 
indefinitely using 100% of the CPU.
I'm using an ext3 filesystem and some directories contains about 250,000 
files.
How can I solve this problem ?

Thanks
Yann
