My first suspect here is that you don't have enough RAM for your index size.

* How many total docs is Solr handling (all cores)?
* What is the total size on disk of all your cores?
* How much RAM does the machine have?
* What is the java max heap?

Here is some additional information on memory requirements for Solr:

When Alessandro asked about the load on Solr, the hope was to find out
your *rate* of indexing and querying, not the load average from the
operating system.  Indexing requires a fair amount of heap memory and
CPU resources.  If your heap is too small, then Java might have to work
extremely hard to free up memory for normal operation.
