Yes, it is constantly growing.
This is how thanos_compact_todo_compactions compares with thanos_compact_iterations_total:

@vincent-olivert-riera can you show us some information about the level 4 blocks you mentioned? What's their duration?

@vincent-olivert-riera if you grep your Compactor's log with block IDs of the blocks that didn't get compacted, do you see anything that stands out? If possible, maybe increase the Compactor's log level to generate more logs (then revert it, otherwise logs might be too spammy). 🤔

@douglascamata , I haven't increased the Compactor's log level yet, but this is what the Compactor is doing (in a loop):

I have search for all the block IDs, but Kibana does not return anything at all.
I will try to increase the log level and see what happens. The log level is debug.
