           Summary: ssh-agent auth socket problem = infinite loop 100% cpu
           Product: Portable OpenSSH
           Version: 4.2p1
          Platform: All
        OS/Version: Cygwin on NT/2k
            Status: NEW
          Severity: normal
          Priority: P2
         Component: ssh-agent
        AssignedTo: bitbucket at mindrot.org
        ReportedBy: focht at gmx.net


ssh-agent is started using .bashrc.

When i update my cygwin installation using "setup.exe" i occasionally
get the ssh-agent hanging eating 100% cpu.

Attached is a debugger session/code snippets which shows the bug

in short: select() is returning "1" while the following accept() gets -1 (errno
= 0x6C). The main while(1) loop leads to 100% cpu usage.

No one on cygwin mailing list cared to answer so i hope someone here can shed
any lights on this.
Maybe this bug is originated within cygwin itself ...

Its very annyoing bug because i often update cygwin installations and have to
kill ssh-agent manually (while eating 100% cpu) to continue.

Regards

A. Focht
