The following issues involving the Web Services (REST) API were found in Spectrum 10.1.1:

Issue 1:   High CPU usage of the OneClick server

Issue 2:   When subscribing for alarms, then creating thousands of simultaneous alarm updates, the rest call does not return any values 

        for some time. 

Issue 3:   Oneclick hangs with "java.lang.OutOfMemoryError: Compressed class space"

Issue 4:   Ping through the REST API call fails with the error "Internal Error: Must add unpack for type java.lang.Integer"

Any environment in which the Web Services API is used

Issue 1:   Java class-loader leak, due to a JAXB dependency

Issue 2:  

a.       Deadlock when the alarm subscription queue is full

b.       Missing attribute ID in updates for requested attributes.

c.       When subscriptions were sent for attributes specifying notify-of-changes=true, updates were sent for all attributes.

Issue 3:   Spectrum was not handling large amount of REST queries using filter criteria.

Issue 4:   The Integer class was not supported by model actions.
