Hi,
We have some strange issue with Almalinux 9.3
After a while of use, rsh no longer works properly on some servers. As soon as the error occurs, I can no longer execute commands (e.g. rsh remotehost uptime). However, logging in to the remote host with the “rsh remotehost” command works.
When checking the service with:
systemctl status rsh.socket, the following output appears:
× rsh.socket - Remote Shell Facilities Activation Socket
Loaded: loaded (/usr/lib/systemd/system/rsh.socket; enabled; preset: disabled)

Jun 20 09:31:52 remotehost systemd[1]: rsh.socket: Failed with result ‘trigger-limit-hit’.
After a reboot everything is fine. (i think for a while)
What could be the reason for the error?
I hope you can help me here, as it would be relatively important.
Many thanks in advance
