## Symptoms

- * High amount of log indexing is observed when multiple lea_session processes run in the background.   

  Average logging rate is 2.5k\~\~  
  Average indexing rates of the offline logs are 32k\~\~  

* Spikes in CPU and system interrupts by the lea_session processes that lasted 30 seconds and have occurred periodically every 3 minutes.   

* All lea_session processes have had CPU spikes (100% CPU with high system interrupts) at the same time, this is because they have all started at the same time.

## Cause

The periodic operation that is causing the spikes is "collect log files list". During the time the lea_session processes are at 100%, Solr can handle less logs.   
In some cases we have seen that while a Lucene Merge was running (not every time), and the CPU / system interrupts spiked, Solr has stopped receiving new logs, until the CPU and system interrupts has dropped back to normal.
