[Clustering/JBoss] - Re: Facing Reincarnation Error?

by bela＠jboss.com

Yes, this is most likely a reincarnation error: the time to detect a crash (in FD) and exclude the crashed member is 46.5 seconds, so when you kill and restart a node within ~ 46 secs, that node will get the same port and be reincarnated. Workarounds (besides using 2.8): - Add FD_SOCK as described on then JGroups wiki - Don't se bind_port in TCP Bela View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4228910#4228910 Reply to the post : http://www.jboss.org/index.html?module=bb&op=posting&mode=reply&p=4228910

[EJB/JBoss] - Re: xercesImpl conflict: How to isolate an EAR deployment

by jaikiran

#2 is what i do for my apps. Can you post your configs? And also the entire exception stacktrace? Also list the jars that you are packaging and the place where they are within the EAR. While posting logs or xml content or code, please remember to wrap it in a code block by using the Code button in the message editor window. Please use the Preview button to ensure that your post is correctly formatted.

[Clustering/JBoss] - Facing Reincarnation Error?

by jtcnz

I am using JBoss 4.0.3SP1 (shipped with JGroups 2.2.7) to combine a cluster with 3 nodes on Win 2003, basing on JDK1.4.2_17. I configured a TCP stack for underlying communication. Both in cluster-service.xml & tc5-cluster-service.xml. See following: <Config> | <TCP bind_addr="10.200.**.1" start_port="7800" loopback="true"/> | <TCPPING initial_hosts="10.200.**.1[7800],10.200.**.2[7800],10.200.**.3[7800]" port_range="3" timeout="10000" | num_initial_members="3" up_thread="true" down_thread="true"/> | <MERGE2 min_interval="5000" max_interval="10000"/> | <FD shun="false" timeout="15000" max_tries="5" up_thread="true" down_thread="true" /> | <VERIFY_SUSPECT timeout="1500" down_thread="false" up_thread="false" /> | <pbcast.NAKACK down_thread="true" up_thread="true" gc_lag="100" | retransmit_timeout="3000"/> | <pbcast.STABLE desired_avg_gossip="20000" down_thread="false" up_thread="false" /> | <pbcast.GMS join_timeout="5000" join_retry_timeout="2000" shun="false" | print_local_addr="true" down_thread="true" up_thread="true"/> | <pbcast.STATE_TRANSFER up_thread="true" down_thread="true"/> | </Config> The problem is, if I turn off one server(say,node B) and restart it immediately, there are ERROR messages: on the B side: 09:07:08|ERROR [ParticipantGmsImpl] handleJoinResponse() should not be invoked on an instance of org.jgroups.protocols.pbcast.participantGmsImpl and after a while also: ERROR [GMS] [B:7800(additional data:18bytes)] received view <= current view; discarding it (current vid:[A:7800(additional data:18bytes)|2],new vid:[A:7800(additional data:18bytes)|2]) on the A side: 09:07:03|ERROR[CoordGmsImp] memeber B:7800 already present; return existing view [A:7800,B:7800] | 09:07:07|ERROR[GMS][A:7800] received view<=current view;descarding it(current vid:[A:7800|1], new vid:[B:7800|1]) After B started up, from the web console, I can see that B joined the cluster view. Is it a proper cluster? Could I just ignore these Error messages? It would be great if someone could explain that what do these error messages mean exactly. What happened behind? Is it typical reincarnation error? Is there some solution to solve this problem? it happens a lot and really annoys me. My solution(it works sometimes but looks stupid): After I turn off one node, I wait for about 4 minutes, then restart it. The Error messages don't show up anymore. Thanks for any idea.

[EJB/JBoss] - Ejb Timer problem: Timer wakes up late when set for long int

by renjith4

Hi everyone, We had a problem with the ejb timers waking up late (almost 2 minutes) while being set for long interval (say 1 month) . Has anyone experienced any similar lag . I searched in several forums and couldn't find any body having similar problems. When the timer is set for few minutes or hour then there is no delay but while setting it for a day causes around 10 sec delay and for longer intervals causes longer delay. Code setting timer is this | final TimerService timer = sessionContext.getTimerService(); | long delay= 2592 * 1000; | timer.createTimer(delay, new Integer(timerId)); | We are using Jboss 4.0.2 [yes we are still in stone age :) ] . Your comments are always welcome Thanks, ren View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4228894#4228894 Reply to the post : http://www.jboss.org/index.html?module=bb&op=posting&mode=reply&p=4228894

[JBoss Cache: Core Edition] - Re: huge memory usage problem

by manik.surtani＠jboss.com

There is a lot of overhead in maintaining the tree structure. The overhead varies with the type of data stored, and if you have a lot of small key/value pairs then the overhead increases quite significantly. This is one of the motivations for starting the Infinispan [1] project. One thing you could do is if you are using pessimistic locking, switch to MVCC which reduces the number of locks created and hence memory overhead.
