Hello everyone. I start to get this error after a long uptime of my PC: Network error: No buffer space available Normally I have many browser tabs opened and some other applications that intensively using the internet but when this error appeared closing even all apps are not solving my problem. It looks like some app incorrectly using network buffer or something broke in windows or probably the problem related to windows sockets I am confused. But it is definitely related to the app or apps that are opening network buffer or sockets and do not close them. Is that any way for me to find a reason without reinstalling the windows? I remember some months ago accidentally I have run one suspicious file but after that, I have checked everything by different antivirus software also I was checking windows file integrity by using sfc /scannow DISM /Online /Cleanup-Image /CheckHealth And I didn't find any suspicious files or activity on my PC only this annoying error. So far no solution. I have to restart my PC ~ every 12 hours or so. Netstat doesn't show me any suspicious socket usage. I am confused.
