The /var slice is only 1.9 Gb here, with about half free. 2) Is it possible to overcome this constraint by: - setting up a new drive with identical slices, only expanding the /var slice, then; - copying the files on the existing drive onto the new drive? Will the FreeBSD & other applications work this way or must they all be installed freshly from scratch?

To: freebsd-questions@freebsd.org X-Mailer: CommuniGate Pro WebUser Interface v.4.2.10 Date: Sat, 02 Dec 2006 08:58:55 -0500 Message-ID: MIME-Version: 1.0 Content-Type: text/plain; charset="ISO-8859-1"; format="flowed" Content-Transfer-Encoding: 8bit After poring over sendmail manuals, docs, readme's and Googling extensively have not found the answer to this question. What configuration settings regulate the outgoing e-mail volume? Have recently upgraded from FreeBSD 4.3 to 6.1 (i.e., did new install of 6.1 on clean disk, installed current versions of applications and moved files - on same server as before, same processors/memory, etc.). Installed Sendmail 8.13 using standard sendmail.cf & FreeBSD.cf in /etc/mail. Have a PostgreSQL database of 20k+ opt-in subscribers to a newsletter. When I invoke the sending routine, sendmail immediately spawns 20 - 30 processes (all I can see via "top"), quickly sends out 150 - 160 e-mails (via /var/spool/mqueue) then no more new processes are spawned and the system returns to a listening state. No error message in /var/log/messages, no clues in /var/log/maillog, nothing in the PostgreSQL logfile to indicate why the e-mails stopped sending. FreeBSD's sysctl shows more than ample system resources (mbufs, files, etc). Netstat -m reveals no denied requests. Is there another FreeBSD mechanism at play? A sendmail configuration setting I can tweak to ensure all e-mails are sent? Any other ideas on a cause of this behavior? Have x-posted to the comp.mail.sendmail group with no replies yet; sure would appreciate any help. Thanks! --_===2537578====twosensemedia.com===_--
