FTP causes 100% CPU on one core

Hello, we have noticed that uploading some kind of files from the inside network to the internet using FTP causes one of the cores of the appliance to reach 100% during the file transfer. Using cpview (PM-Stats) we see that PM: 183_CMI_ADVANCED_PATTERNS_DATA_ seems to be responsible for this high CPU use, but if we disable the IPS (ips off) the issue remains. The same FTP goes through other checkpoint firewalls that don't show this behaviour. Please, have somebody experienced this issue?

Thanks in advance.
