I set up a web server with erlang and use mnesia to save the session.<br>I test server, at beginning, system run well and cpu load were about 90%.<br>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.
