filr indexer suddenly having a very high load (up to 200)
since a few days (probably since sunday) we experience a very high load on our two index servers, after a reboot for some time all is well. Then the load grows again and the filr appliances get unresponsive. The load goes up to 200.
In /vastorage/search/kablink may files are written since January 19. Between December 22 and January 19 no files show up in this directory. We did configure an "optimize search index' to run on Sunday mornings recently. There is enough space on the /vastorage: 400G , 68G used.
How may we lower the load? Is there a way to stop massive indexing? We did the upgrade to Filr 4 at the end of November so the index should be "fresh" enough to need no massive optimizing?
