I have a single node elasticsearch instance ( 0.90 version) running on a
single machine ( 8GB RAM, dual core CPU) having RHEL 5.6, java 1_6_00
After having indexed close to 2 million documents, it runs fine for a few
hours and then restarts on its own, wiping out the index in the process. I
now need to reindex all the documents again.
Any ideas on why this happens? Maximum file descriptors is set to 32k and
the number of open file descriptors at any time does not even come close.
So it cant be that.
Here are the modifications i made to the default elasticsearch.yml file :
indices.fielddata.cache.expire : 5m
I use the elasticsearch service wrapper to start and stop the instance. In
the elasticsearch.conf file, i have set the heap size to 2GB :
How do i go about diagnosing the issue?
