Hi there,

I have just reinstalled OpenVAS from scratch, on a fresh new install of
kali (latest release). I have followed openvas-check-setup guidelines
and everything is marked as OK.
I have updated the default redis.conf file to comment out all "save
lines", regenerated all my certificates, etc...

I start GSA along with openvas-manager/openvas-scanner and everything
works fine for a moment. I can start scans, etc... without issues. 

After around 10minutes, GSA crashes without error message and openvasmd
stop communicating with openvassd (although both processes are up &
running.) 
I can still communicate with openvasmd through omp, but openvasmd <->
openvassd communication is cut. Commands sent by openvasmd to openvassd
remains ignored.

The only way to fix the problem and comes back to a working state is to:

- Stop redis / openvasmd / openvassd
- Purge redis including database and config file
- Reinstall redis from scratch
- Fix redis configuration file again
- Restart everything

I can resume works for some times. But again, as soon as the load
becomes significant, gsa crashes and openvassd becomes unresponsive. 

It's not a load problem are purging/restarting redis is the key. 

Apart from commenting out all save options in redis.conf, is there
anything I am missing with redis to get it work properly ?

I have the following error logs when gsa crashes in openvassd.messages:
