Oversized LOG DB

I usually don't make DB backups manually (automatic backup every day) but today when i was doing server inspection i did manual backup and realized that my LG DB is over 3GB in size. My server is running for a month now and i think if LOG continues grow like this it will soon exceed 10GB. SHARD and ACCOUNT are both in normal size limits. So is there anything i can do to make this LOG stop growing at this rate. I'm using srZor so globals and unique kills are stored in ACCOUNT and only thing i've added that's using LOG is "silk per hour" by caipi. Any kind of help with this oversized problem is welcome
