Hello,

I have a problem with CopSSH 3.0.3 (also 3.0.2) on Windows 7. Average 1 of 5 connection succeed. Sometimes putty freeze during establish  connection , sometimes returns "connection timeout", randomly.  Sshd in debug mode shows nothing interesting, but in system event logger I have following errors:

sshd: PID 580: fatal: fork of unprivileged child failed

sshd: PID 5768: error: fork: Resource temporarily unavailable

I also tried with 3.0.2 version but is the same.

Could you help ?

 

Regards, tc.

It's running in a VMware virtual machine. No virus or malware scanners, no special hardware (except the vmware tools), just plain Windows 7 Ultimate with copssh installed.

Hi, thanks for your feedback.

I have now compiled an rsync 3.0.7 executable without socketpairs (patch 100). It is available for download from here. Replace your rsync copy with this one. Hope it helps.

That would be nice if you report your findings.
