MDM Master Repo getting recurrently broken

Former Member
0 Kudos

Hi

We have a scenario here where there are 2 MDM servers, one server holding the Master Repository and the other one holding one slave.

We are facing serious issues during the synchronization, most of the times the master got broken and we lose the slave needing to recreate it all over again. Rarely, after we create a fresh slave the sychronization is executed sucessfully the first time and even the second time, but afterwards it got broken again.

This behavior started to happen 40-50 days ago, before that the synch was being executed correctly.

I tried to check the logs and noticed the log below is being displayed most of the times.

Could you please advise me where should I start to investigate this issue?

Thanks

Hi Daniel,

Please make sure that the transaction files are never reaching the limit 2GB. Note https://service.sap.com/sap/support/notes/1342483

This can cause broken Master/failed synchronization

Regards,

Gábor
