Compiling slow/frozen on baobab login node


Is there some issue with the baobab login node? I don’t see what could be wrong but I ran a simple “make install” command which seems to be running extremely slowly, or is even frozen. Usually this exact command in the same context takes a few seconds.
It is hanging there:

Scanning dependencies of target rot_doublet
[ 33%] Building CXX object src/CMakeFiles/rot_doublet.dir/main.cpp.o

Is there something weird happening?

EDIT: my make process is using 0% cpu so it must be blocked by something…
EDIT2: It worked well this afternoon… It must just have been a temporary problem!
