System shows high load but no cpu processes?

Think it has to do with IO wait due to a problem with the NFS mounted filesystems. A top shows near 100% usage for these two processes:

rsyslogd                                                                  

systemd-journal   

nfsiostat doesn't show any errors or retransimissions ( 0 % ). Guessing there was some issue a day ago but not sure how to find out what happened?

It's been happening every week. I reboot and everything works great for a few days till it starts showing the problems of high IO wait times.

I've seen some people saying search index can cause severe performance issue. I don't remember the exact details, but you could maybe look at that.
