Summary

0000750: Too many open files

Description

/sbin/udhcpc -v
udhcpcd, version 0.9.9-pre

used
udhcpc -p /tmp/udhcpc0.pid -i vlan2 -s /usr/local/sbin/udhcpc.sh

dhcp server send to dhcp client ip address with lease 10 sec
(terayon tj715 cable modem when connect to ISP fail)

every 10 sec udhcpc renew ip address

Feb 20 19:29:04 udhcpc[29770]: Lease lost, entering init state
Feb 20 19:29:04 udhcpc[29770]: Lease of 192.168.100.33 obtained, lease time 9
Feb 20 19:29:12 udhcpc[29770]: Lease lost, entering init state
Feb 20 19:29:12 udhcpc[29770]: Lease of 192.168.100.33 obtained, lease time 8
Feb 20 19:29:19 udhcpc[29770]: Lease lost, entering init state

on this time I see the udhcpc open and open new socket

in /proc/<udhcpc PID>/fd I see

lrwx------ 1 admin root 64 Feb 20 19:33 0 -> /dev/null
lrwx------ 1 admin root 64 Feb 20 19:33 1 -> /dev/null
lrwx------ 1 admin root 64 Feb 20 19:33 10 -> socket:[76911]

lrwx------ 1 admin root 64 Feb 20 19:33 104 -> socket:[77483]

up to Note: 0002000 socket:[xxxxx]
