Hi Joe,

Sorry for the late reply. We have been fixing bugs and conducting many experiments with heavy I/O to verify the correctness and stability of our storage. This problem I mentioned in this thread cannot be reproduced anymore with these two patches (I applied them back to 3.19.8 and 4.2.8 and both work fine).

Thanks for your help.

Dennis

Hi Dennis,

Sorry to take so long about getting back to you. There was a bug in
the btree library that I mistakenly thought was caused by my fix for
your problem. Anyway, could you try and recreate your problem with
these two patches applied please (patches are against v4.7-rc5 + my
usual thin-dev extras):
