database is locked error

[Mark Warpool]

Hi all,
I've recently started getting a lot of these errors in my mail.warn log.

	Sep 20 16:48:37 mail03 MailScanner[25144]: database is locked(5) at
dbdimp.c line 402
	Sep 20 16:48:40 mail03 MailScanner[24966]: database is locked(5) at
dbdimp.c line 402
	Sep 20 16:49:08 mail03 MailScanner[25144]: database is locked(5) at
dbdimp.c line 402
	Sep 20 16:49:39 mail03 MailScanner[25144]: database is locked(5) at
dbdimp.c line 402

My server is under extremely heavy load at the moment, doing about 30k - 40k
messages per day.  It's a SUSE 10.2 box with dual-dual core Opterons and 2GB
of RAM.  I've been running MailScanner for many years now on various
different servers, but I've never run across this error before.

It seems to be processing mail, however it also seems the mail is piling up
and not processing as fast as I would normally expect it to.  As of this
writing, it has about 1000 messages in queue, where I normally am able to
keep that to the 200 - 400 range.

Any suggestions?

TIA
