on lsof I can see there are multiple entries of the same files opened by elastic search.
The files are in format of elasticdb/data/nodes/0/indices/AW0VfnbAQB-7Z43UAXCUdw/0/index/_1.cfs
The interesting thing is on counting the duplicate occurrence I found that all files are showing the same number. Each file is repeated by 189 times in lsof's output.
Also lsof showing millions of files are opened by elastic search.
How to resolve this ?
Following commands I have used
$ lsof > out.log
$ grep '/flowtracker/lindb/elasticdb/data/nodes' out.log |awk -F '/flowtracker/lindb/elasticdb/data/nodes' '{print $2'}|sort|uniq -c
