Re: offline Durable Topic Subscribers issue in activemq 5.15.8

OK, so I want to make sure I understand this correctly. You have two brokers (or is that two failover pairs?): frontend-standard-01 and backend-broker-name-1. The brokers are not configured in a network of brokers, though you're using your Camel routes to move messages between them. You have some

Re: Transaction interleaving

This sounds like a valid bug. Could you please submit a bug report for it in JIRA? Thanks, Tim On Tue, Nov 26, 2019 at 2:53 AM Viliam Durina wrote: > I'm doing these steps: > > Xid xid1, xid2; > XASession session = ...; > MessageConsumer consumer = ...; > XAResource xaRes = sess

Re: OutOfMemoryError in activeMQ and applcation gets stopped

Are you by any chance using CMS as your GC strategy? It's got a nasty shortcoming where because it doesn't compact Old Gen, it's possible to have heap fragmentation that means it's not possible to allocate contiguous space for a large object even though there's still space free. If so, you should c

Re: Slow consumer on Queue ?

Which Java version is recommended per each version of Artemis?

Transaction interleaving

I'm doing these steps: Xid xid1, xid2; XASession session = ...; MessageConsumer consumer = ...; XAResource xaRes = session.getXAResource(); xaRes.start(xid1, TMNOFLAGS); consumer.receive(); xaRes.end(xid1, TMSUCCESS); // prepare the xid1, continue with xid2 xaR

Re: LDAP authorization with multiple LDAP servers

Dear Justin, thanks a lot for your reply (and please keep me in CC, since I'm not subscribed to the ActiveMQ mailing list). By now I have tried to use a space-separated list of URLs and indeed it seems to work. Very nice! I guess it would be good to mention this in the documentation, wouldn

Hello all, Has anyone managed to check this out? It seems to be a pretty major race condition issue with large message processing. Unfortunately I just realized that attachments get removed from e-mails, so here are relevant thread stacks... Stacks of 2 *deadlocked *threads: "Thread-1074 (Active
