[Dovecot] Possible signed/unsigned bug in libdovecot-storage (2:2.0.14 )

Hello

We are getting following errors when moving mail from inbox to any folder.

"Message has been copied too many times (32767+1)"

lazy_expunge is enabled.

Error messages seems to be from libdovecot-storage.

Any one can confirm the bug? or knows of a work around?


Thanks
K.Z

mdbox? Is it actually copied that many times?

it is mdbox, file size 10M

I dont know if the message was ever copy that many times. I dont know
any way to tell.

I was able to trigger the error message with following.

a uid copy 726974 inbox_2
