    @ustcweizhou Thanks for taking the time to test as well.  I confirm in our testing over
the weekend that we were able to consistently create/destroy/expunge VMs every 2 minutes without
issue.  Before the PR https://github.com/apache/cloudstack/pull/1954 and this PR, we were
having the VPC VR fall over ~8 hours into the test.
    
    In summary, this PR with the one I submitted this morning solved our issues.
    
    Thanks again for the help.

>             Project: CloudStack
>          Issue Type: Bug
>      Security Level: Public(Anyone can view this level - this is the default.) 
>          Components: SystemVM
>    Affects Versions: 4.8.0, 4.9.0
>            Reporter: Joakim Sernbrant
>            Priority: Critical
>
> CLOUDSTACK-6885 changed logrotate from time based to size based. This means that logs
will grow up to its size times two (due to delaycompress).
> For example:
> 50M auth.log
> 50M auth.log.1
> 10M cloud.log
> 10M cloud.log.1
> 50M cron.log
> 50M cron.log.1
> 50M messages
> 50M messages.1
> ...
> Some files will grow slowly but eventually they will get to their max size. The total
allowed log size with the current config is well beyond the size of the log partition.
> Having a full /dev/log puts the VR in a state where operations on it critically fails.
