Timothy Bish reopened AMQ-3573:
-------------------------------
The fix breaks the unit tests in Eclipse and other tools where the temp dir
value is not set as an Absolute path.
adding the following after the tmpDir null check resolves this.
{noformat}
if (!tmpDir.isAbsolute()) {
tmpDir = new File(tmpDirPath);
}
{noformat}
> Hardcoded defaults for systemUsage not suitable for out of the box

> Key: AMQ-3573
> URL: https://issues.apache.org/jira/browse/AMQ-3573
> Project: ActiveMQ
> Issue Type: Improvement
> Components: Broker
> Affects Versions: 5.5.1
> Reporter: Torsten Mielke
> Assignee: Rob Davies
> Labels: default, systemUsage
> Fix For: 5.6.0
>
> Attachments: AMQ-3573.patch

> Right now the default activemq.xml has the entire <systemUsage> section
> commented out. If commented, then the default systemUsage as defined in
> BrokerService.getSystemUsage() applies and uses these limits:
> memoryLimit 64 MB
> storeLimit: 10 GB
> tempLimit: 100 GB
> I don't think these are good default values as in the worst case the broker
> may use 110 GB of disk space. Many runtime environments will not have that
> much disk space and are therefore in danger of running out of disk space
> completely.
> IMHO some more sensitive defaults would be
> memoryLimit 64 MB
> storeLimit: 1 GB
> tempLimit: 1 GB
> to prevent the broker from using too much disk space by default.
> I believe most users of ActiveMQ are unaware of these defaults and probably
> don't expect the broker to use up to 110 GB of their disk.
> If anyone really needs large store and temp limit, they should explicitly
> configure for it.
