RB450G freezes on no-use

Mon Jan 04, 2010 11:35 pm

Everything was working fine on v3.27.
Since upgrading to v4.0 my RB450G freezes when there is no data received/transmitted through the router for a while (have not found if this is on a regular basis, i.e., if router is not used for X minutes).
(RB is used at a school.)

During the daytime, everything is working fine.
In the evening I notice that my website can't be reached from home or any other non-local location, ping is not working and it is not possible to login to winbox/telnet/putty.
I need to wait for several (5-~15) seconds to get a respond (the website opens after a refresh + ping is back + it is possible to login to RB) .

Tried upgrading to v4.1, then v4.2, then v.4.4 - no changes.

Any clues or ideas?
Any more information needed for a possible solution ?

Made a downgrade to 3.30 and the problem solved.

Upgrade back to v4.5, update the bootloader, and then make a supout.rif file after one of these freezes. We haven't seen anything like this, so it would be interesting to see those files.

the file shows only a manual reboot some time ago, and no crashes recently

Thanks for checking the supout file!

Well, it's not like crashes with a reboot. It "just" gets unavailable from the outside (with ping message "Destionation host unreachable") for those 5-15 seconds.
Will try looking harder through some settings and checking the local network - maybe there are some local IP conflicts causing the situation.

My RB450 (4.5) is also have some strange freeze ... let say every few day cpu is going to 100 % ... and Im find (think so) that is something bad with my adsl line ...
Just before one hour traffic is stop and cpu go high ... in that moment I was near and just enable and disable adsl interface ... and everything is back to normal , but sometimes RB450 reboot (if I wasn not there) after some time and I only see in log :reboot by watchdog ...
Look to me like same problem ... but Im think that is caused by my bad adsl line.
Is there some tools which can show what proces cause high CPU? like task manager in windows
