The Claris FileMaker Server 21.1.4 update is now available and includes important fixes that address known issues from previous versions: Key Fixes 1. Field definitions incorrectly read from cache. A bug introduced in version 21.0 caused field definitions to be incorrectly cached, resulting in symptoms such as: Empty related fields Missing value lists and indexes “Insufficient privileges (error -9)” messages 2. Windows only: Server-side script sessions limited by CPU cores. Version 21.1.3 limited simultaneous server-side script sessions to the number of CPU cores on Windows. This impacted I/O-bound environments by unnecessarily queuing sessions. 21.1.4 resolves this by allowing up to 50 concurrent script sessions on Windows before queueing begins—regardless of CPU cores. These sessions may be triggered by schedules, OData, or Perform Script on Server (PSoS). Note: This behavior is not controlled by the AllowPSoS setting. Claris Recommends: To ensure system stability, it is advised to limit active clients to 40 - 45 simultaneous sessions. Exceeding 50 may result in delays, memory overload, or session hangs.
