I googled a bit and tried adding the following arguments

-Djava.security.egd=file:/dev/./urandom
-Dsecurerandom.source=file:/dev/./urandom

but no luck.
Appreciate any help.

Hi,

Anything interesting in your other server logs?

Also, this SO answer may be of interest.

I do not see any issue in server logs. Yes I did as mentioned in link but no luck

Unfortunately, I think this problem is going to be on your database side and outside the scope of SonarQube.
