RocksDB Error - Data Access Failed: IO error - Too Many Open Files

[moisespr123]

When replaying, this error pops up like at above 70% replay (not sure at what percent exactly)

database.cpp:1012             notify_post_apply_op ] Caught exception in plugin: 10 assert_exception: Assert Exception
(s).ok(): Data access failed: IO error: While open a file for appending: /home/{username}/.steemd/blockchain/account-history-rocksdb-storage/022493.sst: Too many open files
   {"m":"IO error: While open a file for appending: /home/{username}/.steemd/blockchain/account-history-rocksdb-storage/022493.sst: Too many open files"}
   account_history_rocksdb_plugin.cpp:589 flushWriteBuffer

This prevents the node from syncing as it prints that error repeatedly.

You'll need to increase the open file limit for your OS. Here is an article on how to do it:

@youkaicountry should this be documented somewhere in the setup instructions? It seems that most people who try to setup an account history node with RocksDB are running into this when they run the node for the first time.
