Failed to unlink SHM sub_ietf-subscribed-notifications.oper (No such file or directory)

[rydy]

Hi,
I'm using version 2.2.19, When "Failed to unlink SHM sub_ietf-subscribed-notifications.oper (No such file or directory)" occurs, netopeer2-server cannot be started. Is there any other way except redeploy sysrepo? What causes this error?

[INF]: SR: Connection 16683 created.
[INF]: SR: Session 16694 (user "root", CID 16683) created.
[WRN]: SR: Recovering module "ietf-subscribed-notifications" operational get subscription of CID 12.
[ERR]: SR: Failed to unlink "/dev/shm/OM_DUsub_ietf-subscribed-notifications.oper.d4cc6de2" SHM (No such file or directory).
[ERR]: NP: Subscribing for providing "ietf-subscribed-notifications" state data failed (System function call failed).
[ERR]: NP: Server data subscribe failed.
[INF]: NP: Server terminated.

thanks.

Is it possible that sysrepo will delete these files?

Please update sysrepo to the latest release and try again.

Can you provide this fix commit? I want to update only this fix.

I cannot because I really do not know, there were hundreds of commits since the version you are using, sorry.

The 2.2.19 version has a open() on "/dev/shm/srsub_o-ran-file-management.notif" failed (No such file or directory). , Are these two errors the same bug?

So what version of sysrepo/netopeer2 is this? Have you modified any compile paths or using any run-time variables used by sysrepo? The file path is completely wrong, there are no .notif files supposed to be in /dev/shm and every .notif file name is followed by the timestamps of the stored notifications so I really do not understand where it is coming from.

I'm using version netopeer2-2.2.19,
run-time variable:

export SYSREPO_REPOSITORY_PATH=/etc/sysrepo
export SYSREPO_SHM_PREFIX=sr

This is also the first time I have encountered this problem. It may happen again after a long time,some logs are as follows
netopeer2-server-srsub_o-ran-file-management.notif_No such file .txt

I see, then like I said previously, I am sorry but I am unable to provide support for too old versions if there were too many relevant changes made.
