Re: Slow KahaDB access

Hi, I have few more queries: 1. IIUC, If there is only one producer sending persistent messages, then journal writes will happen for every message and Slow KahaDB access logging will be done for every message. 2. In what cases does "Slow KahaDB access: Journal read took " will logged? In which ca

What's message ack mode you're using? If your consumer does not acknowledge messages that have been processed, eg, you may forget to manual ack message when using client ack mode or forget to commit session when using transaction, those messages will be redelivered when consumer or broker gets rest

NoSpaceException is also a response come from broker. when asyn send is used,client will not expect response for request. You can try to use non-transactional session or enforce sync send and that should work. 2014-02-20 7:04 GMT+08:00 Gary Tully : > It looks like you are using async send so th

2014-02-19 Thread Hiram Chirino
Yep, at least I've noted that this can happen under consistent load. I think part of the problem is that leveldb is periodically doing level compactions which can cause pauses in it's write operations. HyperDex and RocksDB are both similar libs which we could swap out leveldb for in the future whi

Hi Ram, Assuming both broker instances master and slave work on the same levelDB persistence store. Is it possible that you have some messages enqueued when the master broker goes down? When the slave takes over, it would reload the messages from the persistence store and hence they will be ava

Hi, sadly we once again find some problems with ActiveMq. We are using 5.5.1 but won't be upgrading as we'll probably move to a different message broker. Anyway the current issue is that with producer flow control enabled and with sendFailIfNoSpaceAfterTimeout set to 15000 (15s) we see no except
