I set up a web server with erlang and use mnesia to save the session.
I test server, at beginning, system run well and cpu load were about 90%.
Whe session table size reached a certain value, most web requests were
failure, and cpu were idle. I delete some records in session table, but it
were not worked, then I used mnesia:clear_table/1 to clear session, system
run normal again.
