spontaneous internal error: tried to reschedule a dead thread

[eko234]

Hi, I'm trying to develop a web socket service, and all seems to work well, but I constantly get these errors that say that there was an attempt to reschedule a dead thread, the context for the error is the module rfc6455/conn-api.rkt:134:14. sometimes it takes 5 minutes, other times it takes more but there doesn't seem to be any reason for it, I've tried it on windows and Linux machines, compiled with raco and interpreting the source code, it is a very weird behavior, I hope you can help me out with this.
