Whenever I start up a new Mathematica session, I have to restart the kernel do anything.
For example, if I just enter
1 (or any other command)
into a blank notebook, then Mathematica waits and waits and never returns an answer. It uses 100% CPU while doing so, getting stuck on the command (found using
WolframKernel -wstp -mathlink -linkprotocol -SharedMemory -linkconnect -linkname -dnqwp_shm
To get Mathematica to respond, I have to restart the kernel via:
Evaluation -> Quit Kernel -> Local and then
Evaluation -> Start Kernel -> Local. After this, everything works normally.
My operating system is Linux (Arch), the version of Mathematica is 10.4, though I started noticing this problem earlier (around 10.2?).
I already tried Mathematica 10.0.x freezes in Initializing kernels, but it does not help (and in any case, the problem is not that Mathematica gets stuck at
There seems to be a thread discussing this at: http://community.wolfram.com/groups/-/m/t/344133, but none of the steps help either.
