[Bug 1316433] [NEW] vmware: nova compute memory grows continuously with creation and deletions on VMs
Public bug reported:
nova-compute memory grows to 3gb in a Scaled environment (5000 vm) where
continuous VM operations were executed for 72 hours.
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
22181 nova 20 0 3325m 3.0g 6588 R 34.2 19.0 3984:23 nova-compute
To test the memory leak we created and deleted same number of vms for some iterations. Here is the data .

When analysed with objgraph, it showed that suds library objects occupied most of the memory.
