Amavis trouble with Postfix

    Is it possible that the system is eating up your swap? Do you have something like munin installed on it so that you can check?

    So sorry for the delay I just managed to sit down and try the chmod now!

    I had to use chmod -R 777 /var/run/clamav before anything would work.

    However in mail.log I get this:

    Code:

    Which happens with outbound mail too.

    I am using Munin, however I don't believe that it should effect the mail right? I have 1GB of RAM with 1.5GB swap

    Requested info

    I'm still getting lockups. I'm to the point I'd just like to turn off amavis and clamav and have postfix deliver mail without checking it. Right now when those are manually stopped, postfix's queue just builds. How could I fix that? Here's the info you requested:

    netstat -tap

    Code:
    tempe:/var/run/clamav# netstat -tap

    #
    # Postfix master process configuration file.  Each logical line 
    # describes how a Postfix daemon program should be run. 
    #
    # A logical line starts with non-whitespace, non-comment text.
    # Empty lines and whitespace-only lines are ignored, as are comment 
    # lines whose first non-whitespace character is a `#'.  
    # A line that starts with whitespace continues a logical line.
    #
    # The fields that make up each line are described below. A "-" field
    # value requests that a default value be used for that field.
    #
    # Service: any name that is valid for the specified transport type
    # (the next field).  With INET transports, a service is specified as
    # host:port.  The host part (and colon) may be omitted. Either host
    # or port may be given in symbolic form or in numeric form. Examples
    # for the SMTP server:  localhost:smtp receives mail via the loopback
    # interface only; 10025 receives mail on port 10025.
    #
    # Transport type: "inet" for Internet sockets, "unix" for UNIX-domain
    # sockets, "fifo" for named pipes.
    #
    # Private: whether or not access is restricted to the mail system.
    # Default is private service.  Internet (inet) sockets can't be private.
    #
    # Unprivileged: whether the service runs with root privileges or as
    # the owner of the Postfix system (the owner name is controlled by the
    # mail_owner configuration variable in the main.cf file). Only the
    # pipe, virtual and local delivery daemons require privileges.
    #
    # Chroot: whether or not the service runs chrooted to the mail queue
    # directory (pathname is controlled by the queue_directory configuration
    # variable in the main.cf file). Presently, all Postfix daemons can run
    # chrooted, except for the pipe, virtual and local delivery daemons.
    # The proxymap server can run chrooted, but doing so defeats most of
    # the purpose of having that service in the first place.
    # The files in the examples/chroot-setup subdirectory describe how
    # to set up a Postfix chroot environment for your type of machine.
    #
    # Wakeup time: automatically wake up the named service after the
    # specified number of seconds. A ? at the end of the wakeup time
    # field requests that wake up events be sent only to services that
    # are actually being used.  Specify 0 for no wakeup. Presently, only
    # the pickup, queue manager and flush daemons need a wakeup timer.
    #
    # Max procs: the maximum number of processes that may execute this
    # service simultaneously. Default is to use a globally configurable
    # limit (the default_process_limit configuration parameter in main.cf).
    # Specify 0 for no process count limit.
    #
    # Command + args: the command to be executed. The command name is
    # relative to the Postfix program directory (pathname is controlled by
    # the daemon_directory configuration variable). Adding one or more
    # -v options turns on verbose logging for that service; adding a -D
    # option enables symbolic debugging (see the debugger_command variable
    # in the main.cf configuration file). See individual command man pages
    # for specific command-line options, if any.
    #
    # General main.cf options can be overridden for specific services.
    # To override one or more main.cf options, specify them as arguments
    # below, preceding each option by "-o".  There must be no whitespace
    # in the option itself (separate multiple values for an option by
    # commas).
    #
    # In order to use the "uucp" message tranport below, set up entries
    # in the transport table.
    #
    # In order to use the "cyrus" message transport below, configure it
    # in main.cf as the mailbox_transport.
    #
    # SPECIFY ONLY PROGRAMS THAT ARE WRITTEN TO RUN AS POSTFIX DAEMONS.
    # ALL DAEMONS SPECIFIED HERE MUST SPEAK A POSTFIX-INTERNAL PROTOCOL.

    Can you comment out the last three lines in master.cf:
    Code:
    tlsmgr    unix  -       -       -       1000?   1       tlsmgr
    scache    unix  -       -       -       -       1       scache
    discard   unix  -       -       -       -       -       discard
    and restart Postfix?

    Server still freezing up

    Hi, I commented out those three lines and still, if I run amavis/clamav then after a short time the server totally freezes so that it's not even responsive at the keyboard and only a hard reset restores it. (For example, this time when it locked up I also had an SSH session connected running top and it disconnected me saying "Read from remote host 192.168.1.38: Connection timed out Connection to 192.168.1.38 closed.").

    I also still get the following errors (though the tls ones are new):

    Code:

    Aug 19 08:33:24 localhost postfix/smtpd[6432]: warning: no entropy for TLS key generation: disabling TLS support
    
    I think there are two ways to describe the symptoms: 1) Even with chmod 777 it cannot write to /var/run/clamav which is puzzling; 2) In general terms it seems like clamd and clamscan periodically consume >100% system resources trying to scan queued email for viruses/spam and something in that process isn't working right and it eventually totally locks up.

    Any other ideas?

    Regarding the TLS errors, you should uncomment the three lines again.

    But I have no idea regarding the socket error...
