Sieve problem - Timeout while waiting for lock

[Domenico Pastore]

Hi,

I have an issue with dovecot 2.3.7.2.

When lmtp stores a message into INBOX, I get this error:

2019-10-29 16:32:53 lmtp(“test at XXXX”)<28874><4IPiEytbuF3KcAAAioI89A>: 
Error: sieve: Execution of script /config/dovecot/common/default.sieve 
was aborted due to temporary failure
2019-10-29 16:32:53 lmtp(“test at XXXX”)<23470>: Error: sieve: 
msgid=CE595339-2976-6DFD-FDAD-EEA15CC53218 at XXXX: failed to store into 
mailbox ‘INBOX’: Timeout while waiting for lock

This problem only occurs for one mailbox and when it receives a big 
amount of messages.

With the previous version (dovecot 2.2.15) this did never occur.

The file /config/dovecot/common/default.sieve is in local server, no on 
NFS filesystem

BR,
Domenico
