SUBSYSFS11 Allocated Capacity full ...code108

Hi all

I'm after advice based on some system alarms. Basically the Alarm 108 appears showing less than 5% free space on the Hard disc subfile system. I believe that it's due to the traffic reporting. See prints below;

<ALLOP;

From the above print there is no available disc space on SYSSUBFS11. I also see that traffic reporting is running and cannot dump due to the disc capacity.

1)
Could the traffic reporting be causing the problem? If so what's the process for removing historical traffic records?

2)
What other processes can full up disc space?

This site has very small amounts of customer data entry and is VERSION=LZY2035118/1/R1A (bc9 I think)

thanks
