You could also add it as setting for the fts_xapian plugin parameters?

For machines with low memory, I would like to detect how much ram remains available before starting indexing a mail, so I can commit everything on disk before the ram is exhausted (and break the process)
I tried to put a "fake" allocation to test if it fails, (so it can fail separately, and I can "if ram remaining is above X") but the is really not clean

Hello
I am looking for help around memory management
1 - How to get the current value of "vsz_limit" from inside a plugin (namely https://github.com/grosjo/fts-xapian/ ) , especially for indexer-worker
2 - Is there a macro or function in dovecot to get the remaining free memory from this vsz value ?
Thank you

Hi Joan,

I don't think there is a feasible way to access this setting as of now. Is there a reason you need this? We usually recommend setting vsz_limit=0 for indexer-worker.
