fresh installed?

check your elasticsearch version… 3.2 zammad is only supported 7.5.x elasticsearch version…

try to find other titorial how to installed 7.5 es then installed again zammad…

if you follow official documentation its lead you to install es 7.6 version

3

Rather looks like you don’t have enough memory available.

Provide more information about the machine you have there and if you followed the documentation step by step without changing one of those steps.

elasticsearch version is 7.5 now

The server have 16 gb ram

i have set in the etc/elasticsearch/yvm.options -Xms4g -Xmx4g and ulimit -u is 62987

any ideas?

5

Is the log output the same or did it change…?

6

yes. log output still the same.
I think I haven’t set the right limits but down know how

Please provide the elasticsearch.log from the moment you’re starting ES until it crashes. The reason will be living inside that logfile.

Thanks.
I was able to solve the problem. On the Strato Server I couldn’t set the vm.max_map_count = 262144
After changing the server it works.
