Background Info:
I have a table with a approx 2.5 million rows. The table often gets 200-300 inserts
per second. We are see that the database (7.4.1 Red Hat Enterprise ED 4 way Xeon)
will periodically lock up all of a sudden and force the database to queue up hundreds
of queries. The database comes to complete halt until eventually it clears itself
out. There is other database activity going on but the above activity represents 75%
of the frequency of the queries. The table described above has few reads as we try to
restrict reads. We have it set so it does one read every 20 seconds collecting all of
the newest data in the last 20 seconds and moves it to a reporting table.
What could cause the database to lock up and queue up all the queries?
