{noformat}
For the BLOCKED threads:
GemFireSession.hasDelta is synchronized on the DeltaCapableGemFireSession
instance:
{noformat}
public synchronized boolean hasDelta() {...}
{noformat}
That means one Session Thread retrieved the DeltaCapableGemFireSession from the
server, and the above 86 Session Threads are deepCopying that same instance.
For the waiting threads:
These threads are waiting for another Session Thread to get the
DeltaCapableGemFireSession instance from the server.
So, that is 110 Session Threads that don't have a DeltaCapableGemFireSession
instance. That leaves only 70 Session Threads that could have a
DeltaCapableGemFireSession instance.
master:
A thread dump shows 180 Session Threads.
93 Session Threads are serializing a DeltaCapableGemFireSession in
CopyHelper.copy in SessionEventHandlerCacheListenerAdapter.afterCreate here:

Each of these threads has 1 or more actual DeltaCapableGemFireSession instances
or the bytes for one.
That helps explain why there are far fewer DeltaCapableGemFireSession instances
in 2.2.2.RELEASE than in master and why there is additional memory usage in
master.

> This problem was first observed in Apache Geode 1.11.0. The problem was not
> present in Apache Geode 1.9.2. This problem is an issue for Apache Geode
> 1.10 as well!
> After upgrading _Spring Session for Apache Geode_ (SSDG) 2.3 to _Spring Data
> for Apache Geode_ (SDG) Neumann/2.3, which is based on Apache Geode 1.11,
> this problem with SSDG's test suite started occurring.
> _Spring Session for Apache Geode_ (SSDG) 2.2, which is based on _Spring Data
> for Apache Geode_ (SDG) Moore/2.2, pulls in Apache Geode 1.9.2. This problem
> did not occur in SSDG 2.2. with Apache Geode 1.9.2.
> Out of curiosity, I wondered whether this problem affects (i.e. was actually
> introduced in) Apache Geode 1.10.0. So, I configured SSDG 2.3 to pull in SDG
> Moore/2.2 but run with Apache Geode 1.10. The problem occurred with Apache
> Geode 1.10 as well!
> The SSDG test class in question, affected by Geode's deficiencies, is the
> [MultiThreadedHighlyConcurrentClientServerSessionOperationsIntegrationTests|https://github.com/spring-projects/spring-session-data-geode/blob/2.2.2.RELEASE/spring-session-data-geode/src/integration-test/java/org/springframework/session/data/gemfire/MultiThreadedHighlyConcurrentClientServerHttpSessionAccessIntegrationTests.java].
> The test class was modeled after a customer UC, who were using Spring Session
> and Apache Geode/Pivotal GemFire as the HTTP Session state management
> provider, therefore it simulates their highly concurrent environment.
> The test class has 2 primary parameters: [Thread
> Count|https://github.com/spring-projects/spring-session-data-geode/blob/2.2.2.RELEASE/spring-session-data-geode/src/integration-test/java/org/springframework/session/data/gemfire/MultiThreadedHighlyConcurrentClientServerHttpSessionAccessIntegrationTests.java#L90]

> Size|https://github.com/spring-projects/spring-session-data-geode/blob/2.2.2.RELEASE/spring-session-data-geode/src/integration-test/java/org/springframework/session/data/gemfire/MultiThreadedHighlyConcurrentClientServerHttpSessionAccessIntegrationTests.java#L91].
> The "_Workload Size_" should not be confused with the "_Payload Size_" of the
> individual objects passed to the Geode data access operations (i.e. {{gets}},
> {{puts}}, {{removes}}). The "_Workload Size_" merely determines the number
> of {{get}}, {{put}} or {{remove}} operations performed on the (Session)
> Region over the duration of the test run. Certain operations are "favored"
> over others, therefore the number of {{gets}}, {{puts}} and {{removes}} is
> weighted.
> The "_Payload_" in this case is a (HTTP) {{Session}} object and the "size" is
> directly proportional to the number of Session attributes stored in the
> Session.
> As you can see from the [test class
> configuration|https://github.com/spring-projects/spring-session-data-geode/blob/2.2.2.RELEASE/spring-session-data-geode/src/integration-test/java/org/springframework/session/data/gemfire/MultiThreadedHighlyConcurrentClientServerHttpSessionAccessIntegrationTests.java#L90-L91]
> in *SSDG* {{2.2}}, the *Thread Count* was set to *180* and the *Workload
> Size* (or number of Region operations) was set to *10,000*.
> This had to be significantly adjusted in SSDG 2.3 using Apache Geode 1.11
> (and, as it turns out, Apache Geode 1.10 as well), as can be seen in the
> {{2.3.0.M1}} release bits source,
> [here|https://github.com/spring-projects/spring-session-data-geode/blob/2.3.0.M1/spring-session-data-geode/src/integration-test/java/org/springframework/session/data/gemfire/MultiThreadedHighlyConcurrentClientServerHttpSessionAccessIntegrationTests.java#L94-L95].
> It turns out different combinations of the Thread Count (number of workers,
> or "concurrent Sessions") and Workload Size ultimately determine whether this
> test class passes or not.
> In other words, if I increase the Thread Count, then the Workload Size must
> decrease, otherwise the test fails! If I increase the Workload Size, then
> the Thread Count must decrease, otherwise again the test fails!
> I tried with different combinations of Thread Count and Workload Size until
> the test passed. More often than not 180 Threads with 3000 Regions
> operations worked, but was right on the cusp of failing, therefore, I settled
> on 180 Threads (which nearly matches the customers environment of 200
> concurrent client Sessions) and 2000 concurrent Region operations.
> The point of the test class is to assert the state of the Session is
> consistent at the end of the test run.
> However, before this test can even finish, the client, as in the
> {{ClientCache}} instance, starts failing with Exceptions, specifically:

> Attached to this issue are log output files from each of my runs using Apache
> Geode 1.10 and 1.11.
> The log files serve 2 purposes: 1) to show the version of Apache Geode used
> and 2) the errors occurs on the client and server during the run.
> Any lines in the log output prefixed with "{{[FORK]}}" originates from the
> cache server. The other lines come from the client. There is only a single
> client and server in this test case.
> It takes a bit of initial time during the run for the failures to start
> occurring, which is why this seems like a resource utilization problem.
> After first, I suspected issues with the client Pool configuration, or
> {{CacheServer}} configuration, adjusting timeouts and so on. I even
> suspected memory being an issue for the client and server processes, upping
> each to 2 GB+. However, it turns out none of the changes made a bit of
> difference. And the truth of the matter is, this (existing) configuration
> worked seamlessly until I upgraded to Apache Geode 1.10+ (specifically, 1.11).
