Hi Charles,
Thanks for your answer.

First of all, how can I configure svscan ? I just run svscan-
start /var/service and that's all ( I think ). In terms of pop3, here is
how I start tcpserver in pop.
exec tcpserver -u "$uid" -g "$gid" -c "$concurrency" -v -R -H -t 90 \
-lmyserver \
-x /etc/tcpcontrol/pop-3.cdb 0 pop-3 \
qmail-popup "$hostname" \
checkvpw \
qmail-pop3d Maildir/
In terms of logs, I don't have any message ( like system is not able to
fork... ) just tcpserver common status/concurrency messages.
In terms of kernel I have, by the moment we speak:
proc/sys/fs/inode-max -> 131072
/proc/sys/fs/inode-nr -> 65540 14180
/proc/sys/fs/file-max -> 16384
/proc/sys/fs/file-nr -> 2180 297 16384
/proc/sys/net/ipv4/tcp_syncookies -> 1
/proc/sys/net/ipv4/ip_local_port_range -> 1024 61000
/proc/sys/net/ipv4/tcp_fin_timeout -> 30
/proc/sys/net/ipv4/tcp_keepalive_time -> 1800
/proc/sys/net/ipv4/tcp_window_scaling -> 0
/proc/sys/net/ipv4/tcp_sack -> 0
/proc/sys/net/ipv4/tcp_timestamps -> 0
Number of processes: 360 ( My machine is a Pentium III 800 Mhz, SCSI -
14Gb, 80% full ).
I think there might be a queue of incoming connections that my system is
not able to handle. Is it a kernel issue ?
Thanks again
