Well, as I suspected all along, I think the root of the bug is in the Atheros AR8131 network chip or its driver.
The server was working fine when the network card was an old 3Com 3C905C but after moving the system to a Gigabyte GA-G31M-ES2L mobo with integrated Atheros AR8131, the problem started. There were very occasional and short periods when the webDAV calendars worked but for 99% of the time they did not when the server was running on this mobo. About 2 weeks ago, I moved the system disk again without any explicit changes, but this time to a low power Intel Atom-based D510MO mini-ITX board based system with an integrated Realtek 8111DL and the problem immediately disappeared. Fabio: I still have the problem system if any further evidence is required but I think webDAV has been exonerated and if the bug is to be kept open, the affected component should be changed to something like the AR8131 driver (or the underlying silicon ;>) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/651004 Title: webDAV corruption on Lucid: Lightning calendar not available -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
