Looks like it's not related to graphql_ppx (at least not directly) b/c it's happening when I work w/ other files, e.g. when I transfer some module from other project that includes a lot of components that's not yet implemented and RLS hangs -> CPU 100%.

hrm :/

[alex35mil]

In 95% of cases it happens when error is thrown in graphql_ppx.

FYI I don't see PPX related crashes after I turned off auto rebuild and run bsb -w in console.
