It looks to me somewhat related to below JIRA, but needs
investigation if it would work in below situations.
https://jira.apache.org/jira/browse/GEODE-3649
https://jira.apache.org/jira/browse/GEODE-3580 (Does not look
like FIXED even though it’s marked as FIXED in 1.3.0)

Hi Udo,
Did you get chance to review code?
In below one, I have used ReflectionBasedAutoSerializer, but it’s
same issue with ‘MappingPdxSerializer’ as well.
Please let me know if I can help you with any more samples.
Thanks,
Dharam

Hi Udo,
Sure! I have attached demo project with apache-geode 1.8.0 &
spring-data-geode 2.1.4.RELEASE.
Hope that helps!
Download demo.tar from ->
https://drive.google.com/open?id=10j3NQEkb74n9tNBuWxza9J772p7IYg-7
*_Steps:_*
1. Start locator
$GFSH start locator --name=locator1 --port=10334
--J=-Denable-network-partition-detection=false --log-level=config
2. Start server1
java -jar demo-0.0.1-SNAPSHOT.jar -Ddemo.name
<http://Ddemo.name>=demo-server-1 -Ddemo.port=40440
3. Start server2
java -jar demo-0.0.1-SNAPSHOT.jar -Ddemo.name
<http://Ddemo.name>=demo-server-2 -Ddemo.port=40441
4. Execute below command to suspend server 'demo-server-2'
PID=`ps auxwww | fgrep 'java' | fgrep 'demo-server-2' | awk
'{print $2}'` ; kill -STOP $PID
5. Make sure server 'demo-server-2' is thrown out of distributed
system from logs/pulse
6. Resume server 'demo-server-2' and let it bootstrap and rejoin
distributed system (This will take few seconds so be patient!)
PID=`ps auxwww | fgrep 'java' | fgrep 'demo-server-2' | awk
'{print $2}'` ; kill -CONT $PID
7. Let the member make at least 2 reconnect attempt (You will see
all possible track traces I provided earlier)
Thanks,
- Dharam Thacker

Hi there Dharam,
Given that you are testing with Geode 1.6 + 1.8 and seemingly
you are using Spring Data Geode. Could you possibly provide a
little more information on HOW you are starting the servers?
Also what version Spring Data Geode and maybe, if you could,
a simplified configuration / java classes that cause this to
happen.

John/Bruce,
It’s the same behavior even with “MappingPdxSerializer”

I would really appreciate if we can address into
GEODE-1.9.0 release J
It tries for 6 attempts to reconnect distributed system.
In first attempt it still complains for “pdxSerializer”
issue and in later attempts it always gives,

(Geode 1.6.0)
Hi John/Bruce,
Typo in email was by me but code does not have that.
Here is the detailed logs explaining what might have
happened and looks like a CRITICAL BUG only in both
(1.6.0) and (1.8.0) as well.
[Attached email thread for GEODE 1.8.0 as well]
*_ISSUES:_*
Ø1 common scenario which fails – Member is unable to join
distributed system back after FORCE DICONNECT
ØWhy does PDXSerializer play a role while boot strapping
cache member? (Note : No disk persistence is being used
but only ReflectionBasedAutoSerializer)
ØGMS is throwing NullPointer exception in this situation
ØSame error messages and stack trace for GMS is being
printed once with fatal/error/warn log levels which does
not look consistent.
[Pending] : Dharam to find out if that’s the same issue
with MappingPdxSerializer as suggested by John
Current logs both for GEODE – 1.6.0 & GEODE 1.8.0

Although, there is an apparent problem with your Locator
configuration property, which can/will lead to an NPE
thrown by Geode in this case (as I reported in
https://issues.apache.org/jira/browse/GEODE-6153, which
is not exactly the same as your problem), as Bruce points
out, this is occurring during reconnect.
If the default value of the Locator property had been
used (which it apparently wasn't in this case), then the
node would have failed even on initial startup. So,
something else is going wrong here.

These NPEs are probably not your main problem since
their occurring in a Reconnect Thread. Something bad
happened when you tried to start these caches. They
joined the cluster and then were kicked out for some

tell you what the problem was. Post it or PM it to me
if you want help.
