[Dxspider-support] DXSpider stop responding to connections with 100% CPU

[iz6fxs at cisarmajella.org]

Hi!

 

Please help me troubleshooting this problem. DXspider (cluster.iz6fxs.radio)
suddenly stops responding with the "login" prompt if you connect to it. I'm
running the las build.

When this happens the CPU is stuck to 100%:

 



 

This is the content of the log:

And this is the contect of the last lines of the debug log:

I noticed that all the connections to the node are hung in CLOSE_WAIT
(hundreds if not more):

 



 

I rebuilt the file users.v3j to no avail.

Restarting it with systemd is not working, you have to kill the process
manually to have it restarted.

 

Please help! Thanks,

Norm IZ6FXS
