We've had issues getting sssd to work reliably on compute nodes (at least at scale), the reason is not fully understood, but basically if the connection times out with sssd it'll black list the server for 60s, which then causes those kinds of issues.
Setting LaunchParameters=send_gids will sidestep this issue by doing the lookups exclusively on the controller node, where more frequent connections can prevent time decay disconnections and reduce the likelihood of cache misses.
