but is there no solution in this version or in the future release?


My crystal ball just broke.

All of these pre-sp2 releases are test builds. The ones that are recommended are the ones that have worked fairly well after being tested by users. 12548 is a recommended build.

Try 12548.

Where do I find this version?
[edit]
found it here:
http://dd-wrt.com/site/support/other-downloads?path=others%2Feko%2FV24_TNG%2F
[/edit]

And I would also be happy to have a solution within newer builds.
If its a bug, was it reported to BS?

DD-WRT v24-sp2 (07/22/09) std - build 12548M NEWD Eko
since a few days, doing some https and p2p...

no problem so far, I've http and https enabled (ssh disabled). It seems that the httpd problem is related to newer builds (and hopefully fixed in future releases)...

I confirm the bug also occurs with Intel based platforms.
It also occurs with various Broadcom-based products (tested on 5 different products by Linksys and Buffalo)
It does occur in both v12533 and v13064.
It does occur with sshd/ssh switched off.
It does occur when http is switched off.
It does, of course, vanish when disabling https, which is not a big help, because knowing that a defective service is no longer defective if not started at all is useless.

I can confirm these points for 12548M NEWD Eko
Code:

Mem: 11308K used, 17928K free, 0K shrd, 1388K buff, 4256K cached
CPU: 41.5% usr 58.4% sys  0.0% nic  0.0% idle  0.0% io  0.0% irq  0.0% sirq
Load average: 1.80 1.76 1.70 3/21 8827
  PID  PPID USER     STAT   VSZ %MEM %CPU COMMAND
  274     1 root     R     2616  8.9 98.2 httpd -S

I hope that BS or Eko get notice of our problem...

As I have searched the "timetrac" server (http://svn.dd-wrt.com:8000/dd-wrt/timeline), there has not been a problem posted about what you see. I would suggest the posting of such a problem with the "timetrac" server and the configuration that you use to get the problem. Hopefully if enough people report the problem (or even comment on it), then the developers can located the problem and solve it.

A common reason for these types of problems is the failing to do a hard reset or to install properly.

Make sure you have followed the processes in the announcements carefully prior to posting a bug report. I might try testing this on a unit later today.

I obeyed the flashing rules so this can't be the problem.
I'll wait with the bug report until your testing is complete

These types of problems of excessive CPU use have been seen in the past to be related to issues that are dealt with more fully in the announcements, and installing according the the wiki and those announcements.

I am not seeing this issue. Not a lot of uptime yet though. I will leave this running on my 310n.

I'm experiencing the issue every day Crying or Very sad
1) Do you have any traffic on your router?
2) Have you altered any settings except the http and https settings?
3) Which version are you using?

1. Yes, but it is not consistent. I was on it for quite a while at one point...load went to .12.
2. Only changing the IP address and the settings that you see in the screenshot. Rest is right off a hard reset.
3. The version is in the screenshots.

Hi Murrkf and zorganizer,

you both seem to be experts or at least you know much more about the os of the router than me.
Let's stop the useless chatting and get back to work hunting this bug down!

I'm afraid that I can't help with any debugging info but it seems that some setting causes this problem since Murrkf doesn't experience the problem.

So I'll attach a list of settings from my router. I make these settings after a hard reset to fit my needs.

Tab Basic Setup:
Local IP Address to 192.168.0.254
Start IP to 192.168.0.10
Maximum DHCP Users: 10

Tab DDNS:
Setup a DynDns.org account with force interval of 1 day

Tab Wireless Basic settings:
Wireless mode: g only
SSID name

Tab wireless security:
WPA2 personal
WPA alg.: AES

Tab Services:
3 static leases (MAC to IP)

Tab security firewall:
untick block PING

tab NAT Port Forwarding:
7 Port Forwardings (TCP, UDP and both)

tab Administration Management:
Protocol HTTPS only
Disabel Info Site
Enable Web GUI Management

Thats all I'm doing. Maybe zorganizer recognize one of these settings?!?

greetings,
CyberMCM

Hi,

I'm using DD-WRT for a quite long time now and since a few days (maybe weeks) I'm experiencing an old bug again.
The httpd -S process raises up to 100% of the cpu time.
I have HTTPS webgui turned on but SSH is disabled.

device: WRT54GS V1
DD-WRT build 13064 std

I did a full hard reset (30-30-30).

Anyone else with this config and this problem?

greetings,
CyberMCM

...bug again Sad

I just flashed a WHR-G-54S with 12548 STD NEWD Eko and subsequently with v13064 STD. Enabled HTTPS and rebooted (no other config changes). I logged into the GUI with HTTP and also HTTPS and after a few minutes my load averages drifted down to 0.0.0.0, so I can confirm Murrkf's findings.

Since you mentioned that it takes several days for the symptom to exhibit, do you think it may be related to inbound WAN traffic ?
