Re: server memory & swap eaten up then freaks out

I have a mail and Samba PDC server that, after a couple of days, runs

Does anyone have any ideas of what could be causing this please?

Watch the ten biggest processes, are they growing permanently?
ps aux | sort -nr -k5 | grep -v USER | head -10

Whats about the process count? How many processes running? Is this
number constantly growing?
ps aux | wc -l

I monitored for 2 days. In day one only three staff were in and the server
showed no strain. On day two there were 10 staff. I found that no one
single process consumes RAM but the number of imap instances grows and
grows throught the day, and with it the and amount of RAM and swap used.
Eventually there were 250 imap instances, at which point nearly all of
swap had been used up and I pre-emptively rebooted. I've summarised my
findings below.

Before seeing this issue, this server has run fine for two years with
Sarge, and fine for a couple of months with Etch. Thunderbird 2 was
installed on workstations in December. Other than that barely any changes
have been made and nothing jumps out at me as a meaningful change.
...other than a faulty web app that emailed 50GB of small emails, that
have been manually removed at the command-line from a .Trash maildir
directory with rm so as far as I can imagine are long gone.

If anyone can suggest which way I should progress with this that would be
really appreciated thanks.

This is how it looks right after a reboot:

# ps aux | wc -l
139

# ps aux | grep imap | wc -l
20

# free -m
total used free shared buffers cached
Mem: 2027 379 1647 0 19 134
-/+ buffers/cache: 225 1801
Swap: 2572 0 2572


This is how it looked at 15:20 just before I rebooted because it was
looking as though it would fall over soon:

# free -m
total used free shared buffers cached
Mem: 2027 1961 66 0 232 130
-/+ buffers/cache: 1597 429
Swap: 2572 1772 800

# ps aux | wc -l
370

# ps aux | grep imap | wc -l
250

I'm wondering if these settings in dovecot.conf could be used to fix the
issue:

# Set max. process size in megabytes. If you don't use
# login_process_per_connection you might need to grow this.
#login_process_size = 32

# Should each login be processed in it's own process (yes), or should one
# login process be allowed to process multiple connections (no)? Yes is more
# secure, espcially with SSL/TLS enabled. No is faster since there's no need
# to create processes all the time.
#login_process_per_connection = yes

# Number of login processes to keep for listening new connections.
#login_processes_count = 3

# Maximum number of login processes to create. The listening process count
# usually stays at login_processes_count, but when multiple users start
logging
# in at the same time more extra processes are created. To prevent
fork-bombing
# we check only once in a second if new processes should be created - if all
# of them are used at the time, we double their amount until the limit set by
# this setting is reached.
#login_max_processes_count = 128

# Maximum number of connections allowed per each login process. This setting
# is used only if login_process_per_connection=no. Once the limit is reached,
# the process notifies master so that it can create a new login process.
# You should make sure that the process has at least
# 16 + login_max_connections * 2 available file descriptors.
#login_max_connections = 256
