I stumbled onto this group while trying to find a solution to HG
crashing in Lion... I also noticed that it usually happens when the
system wakes from sleep (e.g., when I open the lid). As a temporary
workaround, I threw together a small quick script that checks to see
if HG is running and tries to restart it if it's not. I invoke this
every 5 minutes with cron. This minimizes my frustrations for the time
being... Sharing below in hopes that it helps someone else until a
permanent fix is provided
(I have also had issues with GrowlTunes crashing, so the script also
checks that--you could easily remove the GT section if not needed.)
To use, copy the script below to a text file, save it to something
like ghwatchdog.sh in your home directory. Then, add a crontab entry
like:
*/5 * * * * /path/to/ghwatchdog.sh
...Of course, if you don't know how to create/edit crontab entries,
you probably shouldn't use my workaround. But I digress.
