Splunk dispatch and srtemp cleanup question

Hi, I want to cleanup my srtemp and dispatch . When users abruptly stop searches in the middle, splunk is creating temp folders etc under srtemp and no cleaning them. ALso clean dispatch command supposedly creates a temp as well, where does that go? How to clean both in Linux recursively using Sudo command. sudo rm -rf /opt/...../dispatch/* does not work for instance. Alike for the srtemp. Thanks.
