Hi Brian, I'm not sure how frequently the scan runs, I will check. The crashes occur about weekly though. This is a security scan, so they check for write-accessible standard directories and all possible buffer overflow etc hacks in the wild ... I suspect we are caught by one of those. We need to check for protocol compliance, the buffer they've sent is clearly garbage. Matevz -- You are receiving this because you are subscribed to this thread.
