@6michel: thanks for the link, but a) I use Android Smartphone, b) on my Smartphone there is no prob in syncing.
I use currently Roundcube 0.9.5 with calendar and calendar_plus plugins, which supports CalDAV for syncing with ownCloud 6.
And only with Roundcube I get many timeouts and often not synced calendar items. I've use the native android calendar with caldav app with no problems.
Yesterday I've upgrade to the latest calendar and calendar_plus plugin, made in the main.inc.php changes like the author of the plugin told.
I see that my apache instances grow sometimes fast.
Do I make something wrong?
Any idea what's going on?
Thanks in advance for your ehlp.
Regards,
Thomas
