I see two problems: 1) indicator-multiload is causing (via dbus?) hud-service to do "something" (update/reload cache?) each time indicators get refreshed. indicator-multiload does not do any "strange" network activity by itself, strace shows quite sane behavior (access to /proc and /sys and such).
2) each hud-service "update" initiated by indicator-multiload is casuing some 0.5MB network exchange (if home directory is on NFS), about half with nfs port and half with nfs lockd. I tcpdumped both sessions. Lock protocol is all binary, looks like repeating lock requests. On nfs port, it does the same over and over again. I counted this snippet called 88 times during one hud-servide "update": q.........O.W.7|N.O... ..yO... ..y............SQLite format 3......@ .........................................................................-.! .....I....I.........................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................W.../..windexapplication_indexusage.CREATE INDEX application_index on usage (application)\........tableusageusage.CREATE TABLE usage (application text, entry text, timestamp datetime) As a workaround, I can: 1) reduce frequency of indicator refresh 2) kill hud-service (and so this network activity stops) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/998759 Title: hud-service frequently tries to accesses non existing files To manage notifications about this bug go to: https://bugs.launchpad.net/indicator-appmenu/+bug/998759/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
