Set ACL Error

[Qmail Dev]

Hello,

I run Dovecot 2.3.2.1 and I keep separate index / control files:


mail_location =
maildir:~/Maildir:INDEX=/liveindexes/indexes/%d/%n:CONTROL=/liveindexes/control/%d/%n

When I try to set an ACL on a folder, I get this error:


Dec 26 17:35:56 imap2 dovecot: imap(user at domain.com): Error:
file_dotlock_open(/home/vpopmail/domains/domain.com/user/Maildir/.Test/dovecot-acl)
failed: Resource temporarily unavailable
Dec 26 17:35:56 imap2 dovecot: Error: imap(user at domain.com): Mailbox
Test: Failed to set ACL


Is it normal for it to try opening the dotlock in the Maildir ?

When I list that directory, the lock file did get created
-rw-------   1 vpopmail  vchkpw        0 Dec 26 17:35
dovecot-acl.lock

Any help is appreciated!
