I guess it could be many things.
Typically an easy one to spot is if you have insufficient heap (i.e.
your 16Gb) and the jvm is full gc'ing constantly and not freeing up any
memory and using lots of cpu. This would make solr slow and "hangs up"
as well during potentially long gc pauses.
add:
jConsole has been used. What have you tried? A simple
top would give you some info.
But 16G of memory out of how much? It's a mistake to starve
the OS, so make sure you leave some memory for the
OS outside the jvm.
This sounds much like a memory issue, here's an
excellent article on the issues:

Hi,
My Solr becomes very slow or hangs up at times, we have done almost
everything possible like
. Giving 16GB memory to JVM
. Sharding
But these help only for X time, i want to profile the server and see whats
going wrong? How can I profile solr remotely?
Regards,
Ro
