First of all, please do (sys:update-allegro) which will get your ASDF up to at least 2.31.9. Then see if the problem continues. If it does continue then I think you will have to provide a bit more detail and preferably an example by which one could replicate your problem. From your description it is not clear if you have several Allegro instances building systems in parallel, or what is going on.

Hi, I am using asdf 2.25 with Allegro CL 9.0, running on clusters with nfs. I noticed some processes would unnecessarily recompile source files, causing other processes reporting no .fasl files error.

Is this a known issue? How can I prevent asdf from such unnecessary recompilation?

Thanks, Yuan
