Manager process never restarts dead worker processes

[SciPlayD]

Worker processes silently die over time and are never restarted by the manager process. This undermines the performance of the cache server until it is restarted, which has to be timed not to interfere with active connections to instances of the Unity Editor. Requesting an enhancement so that the manager process forks new worker processes as necessary.

Thanks for the report!

I published this change to 6.2.4-beta1 if you want to give it a try. It's the only change from v6.2.3. npm install unity-cache-server@beta

Works great, with one caveat. If you kill a process with INT or TERM, the handler at line 166 takes over.

Yes, that's necessary for handling (and testing) CTRL-C graceful shutdown. The KILL signal can be used to force recycle a worker. Anyhow I think the primary use case (to address your original issue) is to catch non-signaled terminations and crashes.

Fixed in v6.2.4 (published to NPM)
