It looks like you are experiencing two main problems:
- A connectivity problem between Apache and Artifactory
- A performance issue with backups
For the second problem (backups) - please make sure you do not backup to zip
archives since it can be extremely wasteful in terms of CPU usage. Also, you
may want to try the incremental backups, which are ultra-fast and
lightweight.
Please also upgrade to the latest stable release. At present it's either
2.1.1, or at least 2.0.8.
Another common cause of slowdowns is using a slow network storage - a slow
network disk or a slow network between the machine running Artifactory and
the network disk.
For the connectivity issue, you are getting a lot of 503 errors, indicating
that the connection between Apache and Artifactory cannot be reliably
established. This can be caused by many reasons.
One reason is poorly tuned Artifatcory VM - in this case you should see
errors in the Artifactory log, usually VM related exceptions, such as out of
perm gen memory errors. The backup problems may also be related to this if
they make the whole VM unresponsive, leading to connection timeouts.
The more common reason is poorly tuned AJP connector settings - check what
errors you get in the Apache log file. When using AJP you have to make sure
the Apache settings and the Tomcat AJP connector settings (in server.xml)
match in terms of number of connections/threads, buffer size, connection
timeout etc. otherwise it can lead to poor performance. The first thing to
check is that Tomcat AJP connector can serve enough requests (check threads
and backlog) and is not overloaded with requests from Apache. For the sake
of identifying if the problem is with your connection setup, you can also
try to switch temporarily to http: proxying (instead of ajp:), which is much
less effective, but is also less prone to configuration tuning problems.
Hopefully that helps putting you in the right direction,
