How to fix liveupdate issue when ESM and SEPM on same server

Hi guys,

I took over a SEPM 11.x server these day, but I found it can't update itself and clients correctly, I found it was because of liveupdate does not function well, then I want reinstall liveupdate, but I found this server also has an ESM server instance running and Liveupdate version is 3.4, it is not 3.3, enven I ran lucatalog -update,but didn't work, so what can I do now? Any solution shouId notimpact ESM functioning, can you guys give me a solution?

Thanks,

Leo
