High IOWAIT: CiscoDRFMaster writing logs like crazy
We have a CUCM 184.108.40.20600-9 running, but this issue also occured when it was just version 8.6.2a.
Our CUCM seems to be rather slow, and when I open the RTMT it says we have high IOWAIT. To verify this, I went to the System Status and I see the IOWAIT is 35%. Now I take a look at the Process list in RTMT, and it seems the CiscoDRFMaster process is using up 30-35% CPU time.
To see what it's doing, I opened the Cisco DRF Master logs from the last 5 minutes. It appeared that this process is writing EIGHT 1MB logs every SECOND, and it's completely filled with this error:
