Telnet gone.

[kbakkbak]

Hello!
At VU+ UNO BH 2.1.6.1 Telnet working some time and then I lost connection and can't reconnect. FTP behave the same. After recever rebooting I can connect again to telnet and ftp.
Have no that problem at BH 1.7 with the same external and internal network settings.
Any advice please.

Does the box have free memory ?

You mean free RAM? Please advice how can I see it?

Can you set up and test with a swap file ?

 

[kbakkbak]

Will do.
BTW when I set up swap file I received OS crash when I start program recording so I removed swap up to now.
Will experiment and report here. How do you think what size of swap file should be?
Thank you for your help!

 

[>>Artorius<<]

Set the swap as big as you can.
Keep us informed.

 

[kbakkbak]

Made swap 1GB.
Nothing changed. Memory go down till zero, but telnet can gone even when free memory still above 50%.
And I discovered that when telnet and ftp have gone the telnetd process still reside.
May be this is some problem in the internal network stack.
Below is current memory info with swap configured as 1TB.

Just found that big quantity of processes

root 17914 0.0 0.9 5288 2508 ? S 10:56 0:00 lo r/run/khubd

arose. There is more than 100 same processes and the number grows.
