I have already run the make check, etc and checked the permissions as per
the LWQ. I have been observing this problem on my system for more than few
days.
Following are the observations.
1. When the incoming rate increases, qmail-send is unable to cope up.
The todo increases at an alarming rate. After this the number of local
deliveries
suddenly stop (around 1 per sec).
2. After shutting down port 25 (to stop incoming mails) and giving some
time for the unprocessed mails to become zero, the local mail
delivery again become fast (I could get a concurrency of about 160)
This is the current stats I have on my mailserver.
isocor:/var/qmail/bin>./qmail-qstat
messages in queue: 67966
messages in queue but not yet preprocessed: 42007
and this is the output of qmHandle -s
isocor:/var/qmailanalog/bin>qmHandle -s
Messages in local queue: 27999
Messages in remote queue: 1418
Has anyone observed this and have come up with any solution to this.
Regards Manny
