iPrint appliance stops communicating with identity source

Appliance 23.4.  People using printers that require authentication will randomly lose access to those printers.  They will not be able to login.  So far the only solution is to reboot the appliance.  Then everything comes back for a few weeks until the problem repeats itself.  Anyone have any thoughts?  I have run the iPrint appliance for years without any troubles and this version is the first to have this issue.

    Hi Ken

    it sounds like :

    OCTCR52A875008 iprint appliance 23.4 authentication service not available

    Check iprint-auth log for this kind of errors:

    2024-01-02T07:07:17.829974+01:00 iprint iprint-auth-service.sh[959]: Jan 02, 2024 7:07:17 AM com.orientechnologies.common.log.OLogManager log

    2024-01-02T07:07:17.830127+01:00 iprint iprint-auth-service.sh[959]: INFO: Caught Network I/O errors on 127.0.0.1:2424/iprintauth, trying an automatic reconnection... (error: com.o; serializable and externalizable flags conflict)

    if it is the same one, restating iprint-auth will fix it for few days. Engineering already looking at it

    Not seeing those errors.  I do see these:

    2024-01-19 06:00:02 WARN  OrientDatabase:205 - Failed to delete the instance in Datastore.

    2024-01-19 06:00:06 WARN OrientDatabase:225 - Failed to get the instances from Datastore.

    2024-01-19 06:00:06 ERROR LdapSyncConfig:112 - Exception while loading config from DB.

    2024-01-19 06:00:06 ERROR LdapSyncService:133 - Final startSync Exception:
    java.lang.RuntimeException: Unable to load Ldap Configs

    Are those possibly related or should I just open a Support Case?

    Hi Ken.  Those errors are consistent with the errors I see in logs I have submitted to engineering for this same issue.  We will update this thread once a fix is available.  As mentioned, if you see the issue again, you can restart the iprint-auth service (systemctl restart iprint-auth.service) as opposed to restarting the appliance, as a temporary workaround.
