I keep track of my RAM usage using iStat nano, and every few days the RAM will swap from 64 MB to 128 MB. The RAM usage will stay at 128 MB until a restart. I checked Activity Monitor, and kernel_task is the big RAM user w/ 1.20 GB of Virtual RAM and 44 threads. Is there any relationship with those two, or are they completely separate? Also, should this be something I keep an eye on RE: how reliable my RAM is? Thanks for any info.
