hi

i have a server with around 6000 mail boxes

it is a dual processor quad core with 4 gb ram
centos 5 with qmail toaster

it contains around 3.5 terrabytes of data

the data is spread over the 2 nrs 2 tb drives

about half the mailboxes have the normal path ie /home/vpopmail/domains/

and the other half has path to the second drive
(i changed the path in the mysql database for around half mailboxes to
point to the second drive)

the machine is accessed by pop / imap / smtp

this was working fine till 2 days ago

i noted that users were not cleaning up the trash folders and space
utilization had gone to 90%. So i ran the qmail-clean-trash script which
cleaned up a lot of trash data. usage is arond 85 % .

this was done in the weekend - ie 2 days ago

now since monday onwards ie the local queue is piling up and delivering
very slowly.

the email traffic send+receive is around 250,000 (around 20 gb of data)
emails per day  with most of the emails being delivered locally.

i have to keep firing perl qmhandle -a -- to get the local emails delivred

but still it is very slow

can somebody let me know the reason for this sudden slow delivery of emails

rajesh
