Too many open files issue on indexer, will increasing Ulimit resolve issue?

[thahir]

Hi Team,

Indexer is going down very frequently due to too many open files 

currently ulimit value for open files on the server is 128000

are we good to increase the Ulimit value more than 200000, if we increase the ulimit value the open file issue will resolve?

if we increase any other impact is there on the indexer.

Kindly assist me on this issue.

Thanks

@aasabatini  Thank you for you response.

we have set the Ulimit as same already like you suggested and thp also disabled. but still we are facing the too many open files issue.

Hi @thahir 

how many buckets have your indexes?

can you check on the path where are stored?

Hi @thahir 

the best pratices suggest to set the ulimit like this:

 modify /etc/security/limits.conf

ulimit -n 65535
ulimit -u 20480
ulimit -f unlimited
ulimit -d  unlimited

use ulimit -a to check the configuration

Also don't forget to disable the THP

Regards

Alessandro
