Zotonic indexer started crashing

[Amiramix]

I updated Zotonic from github and it started crashing:

18:59:17.955 [error] gen_server 'z_mediaclass$omc_web' terminated with reason: {timeout,{gen_server,call,['z_module_indexer$omc_web',{find_all,template,"mediaclass.config",generic}]}}

Does it look familiar to anyone or I need to dig into the code?

I guess we need to give it a bit more time in that gen_server call.

Are you running it on a virtual machine?
Or is your machine quite busy?

It happens only when I edit one of my templates. At the next page refresh I see this crash and it is immediate. I noticed that I don't have the mediaclass.config file anywhere in my site, and that it is present in mod_admin and mod_base_site. It seems that it isn't obligatory because other modules don't have it either, including the blog template site.

I am running from a VM running on my laptop so it's not busy at all.

It is strange because it started happening just 2 days ago. It was all fine until then, I used to have occasional crashes, maybe even the same one, but this time it started happening on a regular basis. And there are no code changes either in Zotonic or my site that would indicate why the problem started just now.

Or maybe z_mediaclass should call z_module_indexer asynchronously, e.g. the indexer would reply immediately with no reply and then post a response later to z_mediaclass pid when the scanning is ready.

BTW is z_module_indexer scanning files on disk with each z_mediaclass request? I noticed z_mediaclass asks 5 times for the same file mediaclass.config each time asking for different media class.
