Hi
I have been using lmdb (with java binding on Ubuntu 14.04+, or Centos 7) to manage daily data sets for a while and so far it works beautifully. Now I am trying to add multi-tenancy support with physical partitioning, but fails to create more than 1024 environments (1017 to be exact). The error msg is "
Resource temporarily unavailable" (not sure if it's accurate since it's from the lmdbjni binding), and it will only generate a lock.mdb of 0 length in the failed environment.
I tuned a few parameters, like reducing the map size to a few MB each, etc, but to no avail.
Is this a hard limit? Or I could change something in lmdb source code to extend it?
Thank you very much!
Jeremy
