Solving problems with LMC

The browser displays a 5xx error when accessing LMC

When services are starting on the LDD system or the system is under a heavy processing load, your browser may
display a 5xx error, such as "500 Internal Server Error" or "503 Service Unavailable," when you try to access LMC.
1
Make sure the system has been running long enough for all services to start. It may take several minutes to start
all services when the LDD system is first booted. If the system was recently booted, or the load balancer is
overloaded, wait a few minutes, and then try again.
2
If the load balancer is under a heavy processing load, try again when the system is processing fewer jobs.
3
Determine whether a problematic server installation is causing LMC to be inaccessible through the load balancer:
a
Try to access LMC directly on each server using the URL http://server:9788/lmc, where server is
the computer on which the server is installed.
b
If you successfully access LMC directly on a server, use the System Status task on the System tab to determine
whether any of the servers in the system are not communicating.
c
If any server is not communicating, uninstall it from the computer where it was installed.
Note: If this is not possible, or if the entry remains after uninstalling, select the non-communicating server
or servers in LMC, and then click Remove Server(s).
d
Try to access LMC using the load balancer address.
4
If the issue is still not resolved, uninstall and reinstall all components, making sure to enter correct addresses for
the database and load balancer where applicable.
