Reporter: ciprian.alexan | Owner: developers
Type: defect | Status: new
Priority: normal | Milestone:
Component: packages | Version: Chaos Calmer 15.05
Keywords: crash load stress |
-------------------------------+--------------------------------
Openwrt CHAOS CALMER (15.05, r46767) is running on Asus WL500gP v1
Router is connected to the internet through PPPoE
One on the wired stations in LAN starts torrent downloading.
As this is a poplar torrent, there are plenty of sources to download from,
it's only the router limiting the traffic.
Download speed starts increasing until the maximum of about 2-3 MBps
Download speed remains stable for 3-5 minutes when router crash.
Router reboot and it comes up.
Download resumes, speeds up, and few minutes later router crash again.
This cycle continues as log as the download is running.
If download stops, router stays up for days serving light internet
traffic.
This is the serial console output the router crashes:
