NMS updates?

Hi, The initialReconnectDelay is the delay for the first attempt only. Is it reconnecting immediately on the first try? Use the maxReconnectDelay to specify the delay for succeeding attempts. http://activemq.apache.org/failover-transport-reference.html Regards, Adrian Co Qian Su wrote: Hi,

NPE in DemandForwardingBridge

Hi, I'm a recent adopter of ActiveMQ 4.1.1 in a simple, two instance "network of brokers" configuration. I'm being burned by the DemandForwardingBridge throwing an internal NPE and dying. I believe this is the same issue as outlined in AMQ-1455. Has anyone else been burned by this and i

Just a hunch, but maybe its the threads package being used on this particular system. For example, on older versions of Linux each thread you spawned was implemented as a separate process. Joe QWERTY? wrote: > > > > ttmdev wrote: >> >> That is rather strange, because the activemq script sta
