Hey @laviregen,

do you often use .lock and .unlock ?

Hello Jean,

In my opinion, the two commands “ds.lock()” and “ds.unlock()” can be triggered by a WebAdmin user when they initiate a compaction or click the “Lock/Unlock” button in the Maintenance tab. They can also be executed by the infrastructure during a database backup, by calling the WebAdmin API, which performs these actions.

Since the WebAdmin is not accessible to clients, the most likely scenario would be the second option.

Hello Ayoub,

We don’t currently use the .lock() and .unlock() commands in our code.

Regarding the logs:

> 1033 2025-04-03T14:00:08.413 [DatabaseManager] INFO - database's write operations successfully unlocked ()
> 1032 2025-04-03T14:00:05.909 [DatabaseManager] INFO - database's write operations successfully locked ()
...

The problem was repaired, and the system has been steady since then.
