You'll notice
Sandbox directory-resolution timeout message now also mentions shared temp dirs as a possible cause
What
When the sandbox takes too long resolving a directory (such as a plugin, suite or case directory, the home directory, or a credential root) and times out, the error message now also lists 'a shared temp dir' among the things that may have been being resolved.
Why
This makes the timeout error more informative when the slow-to-resolve path turns out to be a shared temporary directory, helping with diagnosing why an evaluation stalled.
