'npm install failing when it tries to download dependencies from bitbucket server

When i tried to run npm install command from freestyle job in jenkins It is failing with below error

npm ERR! command-line line 0: unsupported option "accept-new"

I found it is a bug -

[BUG] StrictHostKeyChecking=accept-new causes install failure on OpenSSH <7.6 #31 as per https://github.com/npm/git/issues/31

As a workaround they have mentioned to add

GIT_SSH_COMMAND="ssh" npm install

But after that i'm getting the below error

From detailed log

Could you please suggest how to fix this

freestyle job command as below

jenkins npm-install

From the error code - EMFILE - hitting ulimit conditions. After increased ulimit using ulimit -n issue got fixed.
