Description

Under I/O pressure, with corrupt NSFs, or with slow storage volumes, opening a database can seem to take forever – with the risk that worker threads block and subsequent requests pile up. NSF_OPENDB_TIMEOUT sets a hard upper bound: if an NSF is not opened within the specified number of seconds, the operation aborts and the task can continue with a defined error. An important stability switch, especially for HTTP, Replicator, and Indexer.

Example configuration

NSF_OPENDB_TIMEOUT=60

Notes & pitfalls

  • Values that are too small can cause failing open operations under normal load – verify I/O performance first.
  • Takes effect after a server restart.
  • Pairs with storage monitoring (iostat, storage latency) and with Server_Show_Performance.
  • For recurring timeouts, check the NSF with compact -c -i.
