There are .sah files, in which the data is stored to analyse. So i deleted these files and the client downloads a new package -> new data package.
Yes, it did happen that the segfault reoccured and there is nothing in the dmesg. This was also my first thought, then checked /var/log/messages with a tail and it stucked. No ctrl-c.
Tried this:
#define _GNU_SOURCE 1 #include <fenv.h>
main() { double zero=0.0; double one=1.0; feenableexcept(FE_ALL_EXCEPT); one /=zero; }
...but nothing happens.
