mcalendar worked fine for me initially, but I've now had to remove it from my n810. The problem is that, after I sync it to my Google calendar, mcalendar causes my tablet to spike in cpu/memory usage and then, eventually, to reboot.

When I first started sync-ing mcalendar, I made the mistake of trying to sync it with six preset Google calendars (US holidays, China holidays, Singapore holidays, etc.). The sync took all night (mcalendar had to sync each event individually) and finished with an error. Soon afterwards, I noticed that my tablet would start freezing soon after I connected to any wireless signal.

I put the hometools applet to use and found that my average cpu load spiked from < 1.0 to > 20.0 soon after any Wifi connection. Memory also dropped from about 70000 k to < 20000 k in that same time period before the tablet rebooted itself.

(At first I blamed Midori, Midnight Commander or the mileage app because this problem happened soon after I installed these apps, but I now know that mcalendar was the main cause).

I used the "top" and "ps" commands in Terminal to identify the process that spiked after connecting to the internet. After I uninstalled mcalendar (and manually uninstalled the database file and prefs), I reinstalled mcalendar and everything seemed fine again. However, after another sync with Google calendar (this time successful with only three holiday calendars synced), I started having the same problem again.

I am thinking of submitting this to Bugzilla. According to tso, the specific culprit is mcalendar_sync.python. Like tso, Autosync was unchecked in my mcalendar preferences.
