We stumbled on an issue in which one of our SSO servers (seems to always be the first SSO server in a multi-SSO setup) dumps a lot of krb5 txt files to C:\temp. Over months this folder grew to 7GB with up to 1 million files. This began to heavily weigh down the CPU of the server. Cleaning this folder regularly helps us a lot. Other locations we see large buildups are here:
C:\Windows\System32\config\systemprofile\AppData\Local\CrashDumps *dmp files here
C:\Temp
C:\ProgramData\VMware\VMware VirtualCenter\Logs *dmp files here
C:\Users\*\Desktop *old vCenter support bundles here
