Package: icedove
Version: 1:45.4.0-1~deb8u1
Severity: normal
Dear Maintainer,
Icedove is regularly, and randomly, pegging an entire CPU core at 100%.
This sometimes occurs immediately on startup, sometimes randomly in the
middle of a session, and sometimes it will go back to sensible CPU usage
after a couple of minutes, sometimes it will keep going indefinitely.
I've placed some perf samples and a flamegraph at
http://violet.andrew.donnellan.id.au/~ajd/icedove/ which seem to
indicate that most of the time is being spent in the message database.
FWIW, I do have a very large mailbox - somewhere around 280,000 messages
spread across roughly 20 folders, with one folder having about 200,000
of those messages. The only extensions I have installed are Iceowl and
calendar-google-provider. Unfortunately, I don't really have much more
information to suggest a cause but I'm happy to do more diagnostic work
if you've got any suggestions of what to look for.
Regards,
- Andrew
