Router hangs up transmission

[kovacsrf]

Hi All !

I installed Oleg's newest firmware (1.9.2.7-10) with transmission torrent client using Wengi's manual onto my Asus WL500gx.
The installation was successful and I could start downloading some torrents with transmission.

But after a while (5-6 hours) the router hangs up, it can not be accessible either via ssh or admin web page and internet can not be accessed either.
Only the ping returns. During the period the network download/upload doesn't seem to be very high at all.
I have to turn it off an on in order to work again.

Syslog doesn't contain any error, only the restart can be seen after the last transmissiond entry:

...

Cold somebody help me and give some hints what kind of traces or logs can I make in order to analyse the problem ? Or what should I check ?

Thanks:

I suspect disk problems. Try to shorten USB cable to 20 cm. And do e2fsck -f -y at startup.

Hello,

thanks for your help.
I've already tried it with 2 different winchesters, and both of them were instable.
I read that transmission was developed under OpenWrt firmware,
may be I have to try this firmware too.
The actual winchester is a new SATA2 enabled one with good response time,
As you can see, the load wasn't so high, this disk should have process it.

Today my router broke down again.
Based on the last syslog entry the load wasn't too high (see in red):

After restart the load started to increase fast, see my top output bellow.
Could you give me a tip how can I make logs about the transmission daemon ? Maybe the root case of the problem could be found using the log.

The rapid increase in load condition is most likely as Transmission starts to check the downoaded files - it is nothing unusual.
How much swap space are you using? How many active peers does the torrent has?

[kovacsrf]

My swap is 512M.
One torrent was/is downloading, active peers are about 10-25.
And three others are seeding to 2-4 peers, but sometimes only one seeding is active.

I am using OpenWRT kamikaze 7.09 and is ultra stable.
See http://www.nslu2-linux.org/wiki/Optw...RT-brcm24Build
for details.

[kovacsrf]

Thank you very much !
I'll try this firmware soon, I will report about the result.

[kovacsrf]

I tried to install the suggested Kamikaze firmware but it was unsuccessful.
I got the error message that the version is wrong.

I used the following trc file:

http://downloads.openwrt.org/kamikaz...4-squashfs.trx

Is this relay wrong for my Asus WL500gx ?

Thanks !!!
