You are not alone, many of us have had the same experience. Go back in the post to early Sept timeframe you will find your answer there.

Basically you will need to remove old files in the

i removed the old files, i even removed the old signatures packages, and it is still showing the same disk usage and i have rebooted it, i went to downgrade the sigs but since the AnalysisEngine is not running it will not let me. I am stuck

If the AnalysisEngine is down that can mean several things.

AnalysisEngine will go down temporarily during a software upgrade or signature upgrade. If either one of these operations fails or gets hung, SensorApp (a.k.a. AnalysisEngine) will also get stuck. If this happens, the best bet is to backup your configuration:

copy current-config destination-url ftp://x.x.x.x/backup.txt

and then reimage your sensor.

As per the release note for CSCsb81288 which you've already seen:

- log into service account and become root (use the su command with the same svc acct PW)

- remove the following directories:

# rm -rf /usr/cids/idsRoot/var/updates/files/S69

# rm -rf /usr/cids/idsRoot/var/updates/files/common

# rm /usr/cids/idsRoot/var/virtualSensor/*

# rm /usr/cids/idsRoot/var/.tmp/*

- If not enough space is freed up...

- Also, needed to remove files from:













*Note: after removing these extra files, you cannot perform a downgrade.

To find out what files could be using up the space, issue the command:

cd /usr/cids/idsRoot/var
