Hi there, Recently, I got a strange phenomenon, when I run:
./run guestfish -a xxx.img -a xxx.img
My host system got to be very very slow for several minites, sometimes can`t even move my mouse. I am not sure what I have done made it this way. How should I investigate this issue? Because I don`t see anyone got this kind of problem in FAQ
This happens because of a bug in 'libtool' (or 'sed'/'grep'). The './run' script runs 'libtool --mode=execute', which runs 'sed' and 'grep' on each argument specified on the command line. If some of those files are very large (multi-gigabyte) sparse files, then 'sed'/'grep' takes a very long time to run, and can "hang" your system just as you described.
