Hello,

When Lightning is enabled, there is a large amount of continuous IO, about 30MB/s. It makes Thunderbird so slow that it is not possible to write emails. It crashes often, and it usually crashes when rebooting making it very hard to disable this extension, as crashing then starting Thunderbird is not considered as rebooting then doers not disable the extension. This happens even without any calendar enabled.

Thunderbird 52.5.0 (64-bit) on Ubuntu Lightning 5.4

Thank you in advance for your help!

Sorry, for the delay, the notification ended up in spam.

2. I'll delete one of them because I don't use it anymore (it is always unchecked anyway). Let's see if it helps.

Not to come, but some items indeed repeated often for a while in the past. I'll remove them.

I removed the unused calendar (with not much repeating events, but a lot of them) I also deleted most of repeating events in my regular calendar, in particular the ones repeating often over a rather long period. It's been now few days and Thunderbird is no longer using a huge amount of IO so I consider that it is solved. Thank you a lot, Wayne Mery!
