Marcus Sorensen commented on CLOUDSTACK-1339:
---------------------------------------------
75% memory, sounds like it could be driving you to swap, depending on what else
the server is doing. That would cause the unresponsiveness you mention, and
would be easy to diagnose as such. Again, what sort of hardware is this being
seen on? What does /proc/meminfo look like when the issue is seen? Fortunately
this is also easy to test by changing your tomcat6.conf as mentioned.
It sounds like we will probably need to discuss what sort of memory
requirements are necessary and should be set as a standard. They have increased
with Javelin, but I'm not sure if anyone knows what the minimum acceptable is,
the old settings were running people out of memory, and it sounds like the
current settings may be overwhelming your test systems.
The recommendations per the Javelin e-mails was 2g heap and 512M perm, if we
stick to that, then it means that we probably want to set the minimum
requirements for management server as one with 4GB of RAM. Alternatively, we
can find a lower setting that is acceptable and doesn't trigger out of memory
errors after running awhile, or somehow reduce the actual memory footprint.
