How to make RPi run longer than few hours?

[lockheed]

I need RP to run as headless remote server, but I found that it is not possible to make Raspberry Pi run longer than few hours/days because the ethernet interface drops and there is no more connectivity.

The problem being:

I already tried all the fixes I found, ie:
- smsc95xx.turbo_mode=N
- /etc/sysctl.conf > vm.min_free_kbytes=32768

Nothing helped. So the last idea I have is to restart the networking every minute, like so: http://ubuntuforums.org/showthread.php? ... st13008640
However, this script is for Debian. How could I achieve it in Arch?

[pepedog]

/etc/sysctl.conf is the wrong file, /etc/sysctl.d/10-myconf.conf

Thanks. I hope this will help.

Doesn't look like it's helping. It stopped responding to pings just after 3 hours after booting with new settings:

Do you have a swapfile on your hard drive?
https://wiki.archlinux.org/index.php/Swap#Swap_file

[crashmaster]

For me it looks like your power supply for the hub and/or RPi is the weak spot.

[lockheed]

Well, I power it from Hub through the USB port. I will plug another cable from a spare USB hub port -> RPi microUSB power port and see if it helps.

[zoiner]

I use a dedicated PSU (2A) and my Pi sits headless online for months using Arch. What about the network or router you are linked to?

[lockheed]

My USB hub has a 2A PSU. After connecting RPi with additional hub->RPi's power plug it has not yet crashed. I think that was the solution. It is overclocked like so
$this->bbcode_second_pass_code('', 'arm_freq=1100
arm_freq_min=200
core_freq=550
core_freq_min=75
sdram_freq=640
sdram_freq_min=200
over_voltage=6
')
so it needs steady extra power which its USB port was unable to provide. That is the working theory now and I hope it will stand.

[crashmaster]

Running the RPi so much overclocked is very risky. Don't wonder if extraordinairy effects happen although it seems to run reliable in a first test.
