Unfortunately, I'm currently unable to find it myself, and can reliably reproduce the issue even in a virgin environment. So far, the only common factors (that I see) across each of these has been my Linux host, (CentOS 5.8 at present) and my various tabs/accounts. However, I am at a complete loss as to even guess at how these could affect page faulting on the X server. For reference: on the Linux host, when the Windows host is experiencing these page faults, the Linux host is reporting 20-30% CPU usage overall, no swap usage. --- Erik -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://x.cygwin.com/docs/ FAQ: http://x.cygwin.com/docs/faq/
