David Forget commented on JGRP-217:
-----------------------------------
This issue is also present when using UDP. The workaround is not valid and maybe priority of this issue should be increase.

> Hi,
> I am using jgroups 2.2.9 for communication in my cluster.
> I was checking the behaviour of jgroups to network fluctuation.
> for that I manually unplug the network cable and plug it back after some time.
> But jgroups keeps sending suspected messages and never bring that into the cluster.
> I have two machines in my cluster A(10.200.1.92) & B(10.200.1.74).
> I unplug the cable in machine B. and plug it back . but B never joined the cluster.
> Please find the attachment for the log files from both the machines.
> I am using TCP based communication. I set up my protocol stack using . MPING,MERGE2,FD,VERIFY_SUSPECT,pbcast.NAKACK,pbcast.STABLE,VIEW_SYNC,pbcast.GMS.
> The following are the confuguration in both the machines.

[JBoss JIRA] Created: (JGRP-265) Multiplexer: additional_data is dropped in MuxChannel
by Bela Ban (JIRA)
Multiplexer: additional_data is dropped in MuxChannel
-----------------------------------------------------
Key: JGRP-265
URL: http://jira.jboss.com/jira/browse/JGRP-265
Project: JGroups
Issue Type: Bug
Affects Versions: 2.3 SP1, 2.3
Reporter: Bela Ban
Assigned To: Bela Ban
Fix For: 2.4
HAPartition makes use of the "additional_data" feature to ensure the
unique identity of each member of the partition. This breaks with the
MUX if the Channel is connected before HAPartition gets a chance to set
the additional_data.
This could be a general problem with additional_data -- one service
using a shared channel wants to make use of additional_data, but the
channel is already connected, so all the IpAddress objects in the views
around the cluster won't have the additional_data. This *may* not be a
big deal, as logical addresses (JGRP-129) remove some of the need for
additional data. If people use additional_data for some other reason
than logical addresses, then it may be an issue.
For the HAPartition use case, I created a temporary workaround by
creating an org.jboss.ha subclass of JChannelFactory, and having the
subclass ensure the additional_data is set before handing out a channel.
This ensures that no matter what service starts the underlying channel,
the additional_data HAPartition wants will be there. This will suffice
until JGRP-129 is done, after which HAPartition won't need
additional_data.

> A not uncommon request is to allow for deployments that do not have a qualifying suffix, for example, myejb/ instead of myejb.jar/, mywebapp instead of mywebapp.war
> Most deployers require both a sepcific suffix and the correct deployment descriptor to exist in order to accept the deployment. We should look into supporting such deployments.

[JBoss JIRA] Closed: (JBPM-526) extended exception handling for timer and command execution
by Tom Baeyens (JIRA)
[ http://jira.jboss.com/jira/browse/JBPM-526?page=all ]
Tom Baeyens closed JBPM-526.
----------------------------
Resolution: Rejected
this doesn't fit in the target scope of the jbpm scheduler and timer.
the jbpm out-of-the-box timer and scheduler are targetted for java standard edition. and hence they got some limitations. if you need more features, you need to configure use the JMS based messaging and create a timer service based on the jboss scheduler or quartz. more out of the box support for these latter environments will be created in the near future. hopefully for the 3.2 release

> it should be possible to configure a retry number on a given queue or on a given timer or asynchonous executed command.
> also, a notification scheme should be implemented in case a timer or asynchronous command ends up in the error queue.

[JBoss JIRA] Created: (JBPM-712) Improved Documentation on ProcessInstance Lifecycle
by Ryan Campbell (JIRA)
Improved Documentation on ProcessInstance Lifecycle
---------------------------------------------------
Key: JBPM-712
URL: http://jira.jboss.com/jira/browse/JBPM-712
Project: JBoss jBPM
Issue Type: Feature Request
Components: Documentation
Affects Versions: jBPM 3.1.1
Reporter: Ryan Campbell
Assigned To: Tom Baeyens
Fix For: jBPM 3.2
Detailed design documentation on the lifecycle of a jBPM process.
For instance:
- When are things intialized, when are they saved to the database?
- Can you control the flushing of the HibernateSession to improve performance
- How many threads are created when using asynchronous processing? Is there a setting exposed to control this thread group?
- Can you control how much logging jBPM does as this seems to be a high cost when processing large numbers of events?
