[Dovecot] [LDA] save failed to INBOX: Timeout while waiting for lock

[Frank Bonnet]

Hello

I use LDA Dovecot 2 with SIEVE as Postfix delivery agent and I
occasionally get such message in syslog.

info.log:Apr 13 12:39:40 lda(xxxxxxxx): Info:
msgid=<4DA484FF.5060903 at gmail.com>: save failed to INBOX: Timeout while
waiting for lock

See below the doveconf -n trace

Thanks for any info
