[osmosis-dev] Osmosis error

[Laura Passigni]

Hi,
I have a database openstreetmap like and often I used osmosis to retrieve data and update tiles.

Recently I tried to export from the database with a command like the following:

osmosis --rdc host='xxx' database='xxx' user='xxx' password="xxx" validateSchemaVersion="no" \
intervalBegin="2012-10-09_11:43:00" intervalEnd="2012-10-11_13:55:00" --write-xml-change file="export.osc"

But I received the following error, after about 8 hours:

Could you please help me? 
Please note that I increased also the number of open files to 32758 (before it was 1024), but I received the same error.
Thank you,
Laura Passigni
