Github for windows - ssh-agent.exe using high CPU + 100% disk?

Question

I've just installed Github for Windows on my Windows 8.1 machine and it appears to work fine except that my machine performance drops down dramatically.

Looking at task manager I see that ssh-agent.exe is using a constant 25% CPU (no doubt 100% of one of my cores) and the disk usage is at 100%.

I have had a look on the Internet but can't find any reference to what might be causing this.

Any ideas what might be causing this and how to resolve it?

UPDATE:

I can kill the process and GitHub for Windows appears to keep working but the ssh-agent.exe process starts up again as soon as I close and restart Github for Windows.

Answer 1

Further to moggizx's comment in one of the other answers, I found this was influenced by SourceTree too.

The instance of ssh-agent.exe with the high CPU actually gets terminated when you close SourceTree. Restarting SourceTree does cause another ssh-agent process to be spawned, but the CPU is then idle.

Answer 2

We've seen this happen on occasion due to a race condition between ssh-agent and anti-virus software competing over resources. Do you have any anti-virus software installed? Would you be able to temporarily turn it off and see if the problem persists? We'd be very keen to dig deeper into this if you could reach out to [email protected].

Answer 3

I found the same issue, my solution was to add the file and the process C:\Program Files\Git\usr\bin\ssh-agent.exe to exclusion list in Windows Defender on Windows 10.
