Hi

When I start a scan it goes well for a short while (3%-4%) and then OpenVAS stops doing anything. Load of the machine sinks to almost 0 and ps shows

It seems that there are several machines in the queue but nothing happens.

If I restart OpenVAS the problem persist. I have to stop redis, delete /var/lib/redis/dump.rdb and restart redis.

Any hint on how to solve the problem?
