Ishan Chattopadhyaya updated SOLR-10352:
----------------------------------------
Description:
We should add a warning in the startup script for Linux, if the output of the
following is below a certain threshold (maybe 300?). The warning could indicate
that features like UUIDField, SSL etc. might not work properly (or be slow). As
a hint, we could then suggest the user to configure a non blocking SecureRandom
(SOLR-10338) or install rng-tools, haveged etc.
