Hi,
After upgrading to 1.9.2.7-9 I started to have problem with the udhcpc process taking all CPU. It happends after a about a day or two. Sofar I've restarted the router when it happends after which the udhcpc process behaves correctly for another day or two until it goes havoc again and drains the CPU.
Has anyone else had similar problems with udhcppc in 1.9.2.7-9?
I didn't have this problem with 1.9.2.7-8. I'm running the wl500g which unfortunately isn't supported in the latest 1.9.2.7-10 release..
First I have to thank you and to others who contributed to such great firmwares.
I'll tell you my story about this release.
I was using 1.9.2.7-6b for a long time and for my purposes it was working fine. I didn't have any troubles. Some time ago I migrate to 1.9.2.7-7g and also didn't have problems, except with UPnP which was sometimes working and sometimes didn't (any kind of reset didn’t help). So I wanted to load 1.9.2.7-8, but when I came to this forum I saw that there is newer release. I skipped release 8 and took 1.9.2.7-9, especially because I saw that there are some changes in UPnP (as I explained release notes to me), no more stupid-ftp and support for USB storage with ftp turned off (without manual loading services).
Anyway, I reset my router WL-500g to factory default at web page and with button, flash the new firmware (at web page) and did a quick configuration. Everything worked well, also UPnP. Then I entered all my old settings (manually, but all at once) and UPnP didn’t work, again. I was playing little with settings and I realized that when I turn on WDS (because of my friend with WL-500gP), UPnP didn’t work and when I turned it off it was working well. After reset (turn off electricity) it started to work well (WDS on). After I solved this, I plug USB hub with USB stick and USB disk (ordinary disk in USB case). I followed Wengi-s tutorial to install optware packages. I put /opt on USB stick, swap on disk and installed these packages (vsftp turned off):
When I tried to connect with sftp, it didn’t work (I realized that problem was disk, because it have some troubles and sometimes work and sometimes don’t. Because of disk failure, partitions didn’t mount correct – different dev ID – and I stayed without /opt directory – this partition was auto mounted). I disconnected disk, remount partitions and tried to connect with sftp. I was also looking if correct process was started. Sftp connected, but then I saw that udhcpc is taking 100% of CPU. I restarted router and another try of sftp. Soon udhcpc take 100%. Did this once more and the result was equal. Today I didn’t run sftp, but udhcpc is taking 100 % again after about 16 hours after reboot. So I don’t know if this is somehow connected. I also notice once, that UPnP showed some strange IP (in win xp UPnP status) of my friend computer. IP assigned via dhcp was correct (as I set it in manual assignment at web page settings), but program BCDC++, which opened ports showed IP 0.1.0.1 (in win xp UPnP status). Also don’t know if this has some meaning.Code:[dholliday@mig root]$ ipkg list_installed ipkg-opt - 0.99.163-9 - The Itsy Package Manager nano - 2.1.0-1 - A pico like editor ncurses - 5.6-3 - NCurses libraries openssh-sftp-server - 4.9p1-1 - sftp-server only from a FREE version of the SSH protocol suite of network connectivity tools. openssl - 0.9.7m-3 - Openssl provides the ssl implementation in libraries libcrypto and libssl, and is needed by many other applications and librari uclibc-opt - 0.9.28-13 - micro C library for embedded Linux systems zlib - 1.2.3-2 - zlib is a library implementing the 'deflate' compression system.
My post-firewall file exist but it’s empty. Post-boot has only dropbear and pre-mount line with /opt mount.

I hope this long story will help you and that this problem will be solved. Thank you again and sorry for my bad English and such a long novel.
