I have been able to solve this. We were previously using 4 dual core machines. I have now resorted to using 2 quad core machines instead. On these machines, I have limited index and bulk threadpool sizes to 1 each. This ensures that even in heavy workload 2 cores are free for search threadpool and other OS related functions. This has been working well.
