Listing connections with "tmsh show sys connection all-properties" (please be cautious executing this command as it could have performance impact) will show connections with only a server side whose age is greater than the configured idle timeout. As more zombie connections accumulate, the BIG-IP may run out of memory.
Zombie connections consume memory that cannot be reclaimed. Potential out-of-memory condition.
APM provisioned and VDI (Virtual Desktop Infrastructure) is configured on the affected virtual.
None.
Expired serverside connections are properly torn down.
