I have noticed there's a secd process clogging almost 2,5 GB RAM of my 24. Reboot, PRAM/SMC reset and permission repair do not help. I guess it's some kind of security daemon. Looking at Console reveals many entries like this: secd: SecOTRSFindKeysForMessage SecOTRSession key cache was full. Should never happen, spooky. Can't find this string on Google. iMac 12,1 with 10.10.1. What to do? Thanks!
