Look at timestamps in the log (at level 5), see to which stage
to processing comes and where it stalls.
The state 'A' as reported by amavisd-nanny occurs when a connection
from a client is accepted by Net::Server and the first hook in
amavisd is called.
A state where a task id (like '08733-08') is shown when the message
has been fully received and content checking begins.
In-between the two, the SMTP protocol is goin on (greeting,
EHLO, MAIL FROM, RCPT TO, DATA), connection to LDAP and SQL may
take place, etc). Examine the log and see.
The following patch may be applied to 2.4.4, which will insert two
additional nanny states B and T, so the sequence as shown by nanny
would be:
- '' (empty string) when a child process is alive but idle
(e.g. before a connection is received, and then again
after response to MTA has been sent);
- 'A' Net::Server just accepted a new connection;
- 'B' (new) protocol begins (e.g. SMTP is about to send a greeting);
- 'T' (new) SMTP transaction begins (when valid a MAIL FROM is received);
- an id like '08733-08' shows during contents processing;
- '.' a dot shows when content processing has completed and
the protocol is about to send response to MTA client;
