After an emerge --sync many packages (the ones that are more complicated) "freeze" I don't know if its an actual freeze or simply a huge slowdown where the mouse becomes very jittery. Eventually freezes. One of such packages is mysql, DBD-mysql for perl, Reproducible: Always Steps to Reproduce: 1. emerge mysql 2. 3. Actual Results: everything works fine. Eventually during compiling (about 20minutes in) mouse becomes jittery and the entire machine slowly starts to slow down to a gradual freeze. Expected Results: get mysql I don't know if this will work for mysql since I have went through other means of getting it. Going to /etc/make.conf MAKE_OPTIONS="-j3" changed to MAKE_OPTIONS="" which seemed to have fixed compiling problems as I was able to install more packages. However haven't tried on the packages that failed before though.
So type `free` or `cat /proc/meminfo` when your box is slow, and post the output.
