Autogrow problem

We are seeing an issue with the autogrow setting on some of our production
databases. Occasionally we will see a database fill up, processes trying to
write to the db will show page latch waits and the database will not grow for
up to five hours. The last time it occured, the database only needed to grow
400MB but it did not for hours. Once it did grow most of the writes which
had been waiting did not occur. Their is plenty of space on the disk and the
server was not at capacity. Any ideas?
Thank You.
Autogrow is a necessary evil...you should be maintaining your data and log
file sizes based on the expected amount of transactions and altering them
during maintenance hours. Autogrow ought to be a failsafe only due to the
performance impact...
