Hi team! I’m using dagser 1.1.21. Dagster daemon stucks after runing for a few days. with

ps

command, we found dagster daemon run two python process, but they become defunct process ( referer to 1st pic). with

py-spy

, we found dagster daemon is waiting for these two python process ( referer to 2nd pic). after reading source of dagster/_serdes/ipc.py:216 and dagster/_grpc/server.py:1123, we found it’s trying to run a grpc server in a sub process. what can i do to prevent dagster daemon stucking? P.S. we also noticed that dagster/_serdes/ipc.py:216 changes in https://github.com/dagster-io/dagster/pull/11737 and https://github.com/dagster-io/dagster/pull/13525, and dagster 1.1.21 is after #11737, so we try to apply code source changes in #13525 into ipc.py( remove

preexec_fn

argument), but the problem still happends
