[ROS v5RC1] CPU Load at 100% on SSH Logout

RouterOS General
1

Hi,

I ssh into my MT Box and do somthing - after /quit the CPU Load is at 100%. Only a reboot helps!

I have this problem on a RB800, RB433 and x86 all ROSv5RC1

velvet

BTW, any ETA for RC2?

2

just tried my RB800 on the table, login user with password, did something (/ip addr p; /ip ro p;/sy reso pri) then /quit

logging back in and everything is as usual.

log in:

[admin@x86] > /tool profile
NAME             CPU        USAGE       
winbox           all        0.5%        
logging          all        0.5%        
management       all        0.5%        
idle             all        98.5%       
pppoe            all        0%          
unclassified     all        0%

log out and log in again:

[admin@x86] > /tool profile
NAME             CPU        USAGE       
ppp              all        0%          
firewall         all        1.5%        
logging          all        0%          
management       all        53%         
profiling        all        14%         
bridging         all        1.5%        
unclassified     all        30%

I tested again on rb433 and rb800 and this time I waited few minutes - CPU is on2 % look good! only an my alix board CPU Load is still 100%

4

after 3 hours rb stop working with cpu usage 100%
only reboot helps for next 3 hours

5

after 5 mins CPU Load OK on rb433, CPU is at 100% again.

[admin@rb433] > /tool profile 
NAME             USAGE       
wireless         0%          
console          0.5%        
dns              0%          
winbox           0%          
management       56.5%       
profiling        0%          
queuing          0%          
unclassified     43%

have to find what that unclassified process is. as i see it ssh processes are identified correctly and that is something else that is using up your CPU.

7

the system is idle all the time until I ssh to the Box!
you can not reproduce it? login via ssh few times and /quit and you should see the 100% CPU Load.

8

I also have this problem but i am using Winbox … CPU Usage for “Management” goes very high (total CPU usage of the box is 100%) for a long time… only reboot really helps :frowning:

9

this is fixed for 5rc2, so just wait for it.

10

yes, rc2 works for me!

11

Similar problem on Ros 5.0rc5. Please fix it.

I ssh into my MT Box and do somthing - after /quit the CPU Load is at 100%. Only a reboot helps!

Confirmed, same problem on RB433AH with ROS 5.0rc5.
After ‘quit’ from SSH session CPU is 100% busy.
Profile tool from Winbox shows:
management - 60%
unclassified - 40%
Next SSH connection, even without login reduces CPU utilization to typical level.

Regards, Grzegorz.

wait for 5.0rc6 release.

5.0rc6 → CPU Load at 100% on SSH Logout not fixed!

v5rc6 released
