/var/log/ has only 0% free | Big-IP PEM

Hi all,

Unit: Big-IP Policy Enforcement Manager (PEM)

Software: BIG-IP 13.1.1 Build 0.76.4 Engineering Hotfix

Issue: /var/log/ has reached full capacity.

We have started receiving Broadcast messages when connected via SSH, stating that Disk partition /var/log (slot 1) has only 0% free. As our regular F5 administrators are away I am unsure how to proceed.

Broadcast message from root@hostname (Wed Jan  9 13:01:02 2019):

011d0004:3: Disk partition /var/log (slot 1) has only 0% free

Here is the disk usage from /var/log/ and the culprit looks to be wr_urldbd.out. As shown below it's at a staggering 34G. We have another identical unit at another site which has this file @ 8.4M.

[user@hostname:/S1-green-P::Active:Standalone] log  ls -Slh | head -10

total 6.8G

Tailing wr_urldbd.out yields -

`[user@hostname:/S1-green-P::Active:Standalone] log tail wr_urldbd.out

nGetRtuUpdateInfo: failed sConnectSocket to service.brightcloud.com failed connect to 570354308 on 8888, err = -1

As this unit is relatively new to our network, I suspect that configuration is yet to be finalised which is why it's being blocked - and I'm not too worried about that. What'd I'd like to know is the purpose of this file and if it would be safe to delete it?

Thanks in advance.

First time poster so please let me know if any additional information is required.
