Looks like your system isn't automatically resuming interrupted system calls.1

You could try modifying the module's code in order to do it manually.  Resuming a system call manually means to simply call it again if $! is EINTR or ERESTART.  In this particular case, look for line 755 in OpenSSH.pm 

    $r = waitpid($pid, WNOHANG) and last;

and modify it to read 

    do {
        $r = waitpid($pid, WNOHANG);
    } while $r<0 and ($! == Errno::EINTR or $! == Errno::ERESTART);
    last if $r;

[download]

This should take care of this particular waitpid call which produced the message in the debug log.  There are more, though, which would likely need a similar treatment, so it's probably best to get in touch with the module's author... (he frequents this place regularly, so he'll probably see the thread sooner or later, anyway).

1 System calls may be interrupted for a variety of reasons. The more loaded a system, the more often it happens.  Most systems these days automatically resume them, so code isn't always written to handle the rare case where you have to do it manually...
