Bug #78808 [Opn]: [LMDB] MDB_MAP_FULL: Environment mapsize limit reached

Edit report at https://bugs.php.net/bug.php?id=78808&edit=1 ID: 78808 Updated by: cmb@php.net Reported by: progr-d at yandex dot ru Summary: [LMDB] MDB_MAP_FULL: Environment mapsize limit reached Status: Open Type: Bug Package: DBM/DBA related Operating System: macOS 10.13.6 PHP Version: 7.3.11 Block user comment: N Private report: N New Comment: From the docs[1]: | Default size of memory map. This is certainly too small for any | actual applications. Apps should always set the size explicitly | using mdb_env_set_mapsize(). So yes, there likely should be some dba_open() argument to allow for a custom map size.

How can I fix this? Now, probably, I can only recompile the lmdb library...
