XRDP Service Keep on getting stopped

[AbinayaSandhiyaM]

On our RHEL8 Server XRDP service getting stopped/dead automatically.

And based on the log could see below messages

xrdp/xrdp.log
[20240125-07:22:35] [ERROR] [ITU-T X.224] Connection Sequence: CR-TPDU (Connection Request) failed

[20240125-08:52:52] [DEBUG] Closed socket 11 (AF_INET6 :: port 3389)

Could any one let us know what could be the reason for this failure.

Since we been using XRDP on different machine like RHEL7, 9 etc.
But recently on one our newly configured RHEL8 machine facing this sudden xrdp stop/dead issue

Hi @AbinayaSandhiyaM - welcome back.

Your xrdp process is receiving a SIGTERM (or possibly SIGINT) signal from another process:-

[20240125-08:52:52] [INFO ] Received termination signal, stopping the server accept new connections thread

Check your system logs for system activity just before this time with:-

sudo journalctl -S "2024-01-25 08:52:47"

If that doesn't give you any clues, you may need to track down the sender of the signal. This can be hard. Have a look at RHEL knowledgebase #165993. This is for SIGKILL but can be readily adapted for SIGTERM. It also contains links which I can't follow, as I don't have a RH account. As you mention RHEL, I'm assuming you do.
