mongodb mongorestore assertion failure

Question

I've mongodb version 1.8.2 running on production, for which a cron job runs for database dump. I've just upgraded my ubuntu to 12.04. Now I m unable to restore any database/collection. It's giving

db.system.indexes Assertion failure _filename.empty() util/mmap.cpp 167

I googled for it, but can't find any suitable answer.

Answer 1

Try setting ulimit -n 64000 in the startup script, usually, /etc/init.d/mongodb. This worked for me.
