Hi all,
Now I have different scenario I have mono running as a custom user
XYZ...however I am getting exception that mono can't write keypairs to
follow in path
/root/.config/.mono/keypairs
Why it's trying to write key's to Root's path......
I am using nginx+fastcgimono ...
And this issue is very random I got 3/10 times...
Please help urgent

And following error is coming randomly not always.
I don't want to run my application as root user for Security reasons
