imap MOVE produces duplicates due race

hello,

I meet the issue with MOVE command race in concurrent sessions - with 
cyrus 2.5 it produces duplicates:

=========> first session

GBS3 OK [COPYUID 1634534758 3 2] Completed


Is there any way to avoid duplicates creation by MOVE command in 
concurrent sessions ?
Was the issue fixed in 3.x branch ?


Best,
Deniss
