Temp drive Filling up

Hello ,

I have noticed the following problem on our VUM server :

The folder c:\Users\<vcentersvc account>\appdata\local\temp is filled up with thousands of folders like Jetty_0_0_0_0_9084_vum.fileupload.war__vum.fileupload__dgjc5a_2779239831347539395

Therefore my C. drive is filling up rapidly.

I cannot find any information about those folders.

Any idea what there are and how to get them cleaned up ?

Cheers,

V
