Please note that there is no point in saying what time something happened unless you use GMT (UTC). You say it was 5 am but your profile doesn't even say where in the world that you live, so we don't know which time zone you are referring to.

One way to see about memory usage is to run the linux-Unix top program. My machine has an 8-core processor pretending to be 16 cores because it is hyperthreaded, but I told it to run at most 8 boinc processes. I told top to show only boinc processes. It shows I have about 64 GBytes RAM, and the three climateprediction ones are taking about 1,3 GBytes each; near completion, these take up abour 1.4 GBytes each. They saturate the 8 processors I allow to boinc. With my version of Linux, I have about 54 GBytes of RAM available.
