ADF application load testing with 400 users presents stuck threads and deadlocks related to MDS (in less than 5 minutes)

ExecuteThread: '1'
- waiting on <0x1ab2cd3e> (a oracle.mds.core.CachedMOProvider
- locked <0x4fg5hi6j> (a oracle.mds.core.CachedMOContent)
ExecuteThread: '3'
- waiting on <0x4fg5hi6j> (a oracle.mds.core.CachedMOContent)
- locked <0x1ab2cd3f> (a oracle.mds.core.CachedMOProvider)


Turning off "Detect Metadata Changes" and "Allow Unbounded Task Flow Customizations" options in adf-config.xml do not help.

Setting the MDS cache size to unlimited in adf-config.xml can improve situation, but issue may reproduce either way after 30 minutes of execution.
