How to stop a scan process?

Hi,
When a FW was added to monitoring, Oputils added automatically de subnets configured in the routing tables of the firewall. Some networks have mask 255.255.0.0 and when de scheduled task to scan the IP is taking about four-five hours to scan each subnet, so the servers' disk is writting all day and the OPM server is become very slow.
How can stop the scan process without reseting the Opmanager service ?

IN addition, the publishing functionality is not working because there is no "index.html" file in each subdirectory created when publishing, and the only way to access the reports is going to each folder in the installation directory /IPAMpublish/ and double-clicking the htm file created (as intance: 2017_07_10_17_32_58.html)

Ihave installed the last consolided servicepack (June 20th) but this doesn`t resolve th IPAM asn SPM publish options.
