I have Zammad running for 9 months without interruption. Suddenly (no updating from my side involved), the customer dropdown of new tickets was not anymore working. I realised that elastic search is down and throws the following error:
[root@ticket ~]# systemctl status elasticsearch.service
● elasticsearch.service - Elasticsearch

Does anyone know this error message and a potention fix / work-around?
Thank you very much!
