SVLive1 Maintenance

MLS Service Account Expiry

The MLS application runs on a server hosted within the client network. The network service account for the MLS application is usually set up to run under the NT AUTHORITY\NetworkService account.

If this is not the case and IT has assigned a service account to MLS, the password for that account needs to be set to never expire. This can be achieved by monitoring the validity of the designated service account and renewing before expiry.


Impact on Service

If the service account expires, all SVLive1 services would become immediately become unavailable with data loss throughout the duration of the outage.

MLS Server Shutdown

The MLS Server may be shut down by your IT team team due to routine maintenance. It is recommended that any shutdown of the MLS server is done outside of the hours a customer may want to collect utilization data or use Wayfinding technology. Additionaly, your IT team will need to notify the Corporate Property team of the outage.

Also, when Serraview Support team and the Client IT team are checking:

  • the connectivity between the Client's MLS and Serraview web services.
  • that the MLS is running on the Client's server.

Client IT will be instructed to perform a restart on the MLS server.


Impact on Service

If the MLS server is not running, all SVLive1 services would become immediately become unavailable with data loss throughout the duration of the outage.

Follow the instructions here to Start and Stop MLS Server.

MLS throwing VLAN Timeout Error

MLS is unable to scan VLANs throwing a timeout exception error. For example:

<time> ERROR SwitchMacToPortFetcher(EasyNetQ consumer dispatch thread) - Error scanning - vlan x ... vlan-x [Exception of type 'Lextm.SharpSnmpLib.Messaging.TimeoutException' was thrown.]


  • This error appears when clients have updated their switch firmware.
  • The MLS has code that includes the @ character when scanning for VLANs or if it exists within the community string, it will crash, throwing a timeout error. 

For more details, refer to Wireup Maintenance for SVLive1.


You need to reconfigure their switches by removing the @ from the community string and the Serraview team to update the Community string field within the MLS accordingly.
