IMAP message sync is time-based and does not care about the size of your folders, just the message density.  Tarako has limited memory so this is much more likely to be a serious problem for it.  Can you clarify "hang"?  I expect we'd just run out of memory and crash and that would be the end of the story for us, so a hang is surprising.  Providing a logcat per https://wiki.mozilla.org/Gaia/Email/RequiredBugInfo will help us better understand what is happening.

Bug 823384 for partial day sync is the likely bug to dupe to if we're OOM'ing, although other Tarako bugs relating to memory usage may also be relevant.

I can loan a tarako device to Rachel to allow her to reproduce this again so that we can get a logcat with the required email logs.

Rachel - Can you help answer comment 1?

I worked with Rachel to try to diagnose this, but we were unable to reproduce this with multiple attempts.
