[jboss-user] [JBoss Messaging] - mysql persistence performance - high load + deadlocks
ENV:
JBoss 4.2.2
JBM 1.4 SP1
MySQL 5.0.x
From within an EJB3 slsb we pump about 600,000K messages into a
clustered topic daily using XA transactions, which is consumed by 4 separate clustered
durable subscriptions (this occurs in a cluster of 3 jboss nodes). When we use persistent
messaging we see lots of deadlocks in mysql and a high unix load. When we don't use
persistent messaging the deadlocks and high load goes away.
My question is have you all come across this also and is there any configuration work
around to lower the load and deadlocks when using persistent messaging?
Thanks,
~Jonathan
