100% CPU after interrupted connection

Hi Michael, i use the Virtualhere server on my OpenWrt RT3xxx router. Sometimes my Wifi connection is not that stable and connection from the client gets interrupted.
When it connects again it will show "in use by ...". Off course i can disconnect the user in the --admin mode of the client, but the CPU of the server is already at 100% (permanent!), making the Wifi very slow and connection almost impossible.

Wouldn't it be better to just disconnect the user at the server when the TCP/IP-connection gets interrupted ? Or maybe there is another solution for this problem?

My workaround is that i have to log on to the router, search the procesnumber of the Virtualhere server with "ps" and "kill" that proces by its number, then restart the server...

I hope to hear from you. Greetings, Evert


Hi Evert, actually virtualhere already does automatically disconnect the user if there is a TCP error or a client ping timeout. If its getting jammed its probably because it is getting no response from the openwrt kernel when it should get one. Do you have gdb on your openwrt box?

If so i will compile a debug version of the server for you. When it gets jammed just run "gdb attach
" then "thread apply all bt" that will show where it is getting stuck.


Yes, I managed to install gdb through the entware-repository. I now have:
