In 5.3, the approach is to leave the data in the old format until it is requested, and then update it on the fly as it is vended to the client. This fails when there are enough events being 'touched' by the request that the processing time for doing the format upgrades exceeds the client's request timeout threshold. This is fixed in 5.4-dev.</div><div class=""><br class=""></div><div class="">Be sure to have backups before you do anything :)</div><div class=""><br class=""></div><div class="">-dre</div><div class=""><br class=""><div><blockquote type="cite" class=""><div class="">On Feb 3, 2015, at 2:23 PM, Jacques Distler <<a href="mailto:distler@golem.ph.utexas.edu" class="">distler@golem.ph.utexas.edu</a>> wrote:</div><br class="Apple-interchange-newline"><div class="">* CalendarServer 5.3<br class="">* Clients: Calendar.app on MacOSX and iOS.<br class=""><br class="">All of a sudden, I am getting a lot of<br class=""><br class=""> [twext.web2.channel.http#error] Connection aborted - took too long to close<br class=""><br class="">errors in my logs -- essentially every time the client tried to manually refresh the calendars.
