3. Re: Is v1.4.1 completely compatible with v1.4.0
liuhang781102 Feb 29, 2008 12:38 AM (in response to liuhang781102)I am sorry the flags in the config content is missings when showed in the page.
Now I have another idea. Can I delete a member from one cache's member view (delete the other member who has essentially died)? If it is, How can i do it? -

That's not the way to go. It is JGroups's failure detection protocol(FD) that should manage member removal/addition. I suggest you read /tune the Failure Detection section in the JGroups manual -

liuhang781102 Mar 4, 2008 8:44 AM (in response to liuhang781102)I read some articles about FD ,but I can't find a configration that ompletely avoid this problem.
I tried to cope with this question by modify the emberlist or reconnecting the channel. But soon find them doesn't work .
Finally I recreate the channel and solved the problem to solve this problem. If somebody have good ideas about FD configration , just reply to this post , I'll be very appreciate . Our next version of product may take this solution. -
