Inconsistent behaviour by Spring Quartz Scheduler.

Hi,

I have a Spring Quartz scheduler which is clustered on multipele servers. The quartz properties are loaded from spring context as follows :




Now, here is my problem. Sometimes the Cron trigger doesn't fire at all and i get the following error on my console:

2011-09-12 06:24:20,804 [QuartzScheduler_Quartz Scheduler-testserver.corp1315801853523_ClusterManager] WARN org.springframework.scheduling.quartz.LocalDataSourceJobStore - This scheduler instance (ORLLA001.curascript.root.corp1315801853523) is still active but was recovered by another instance in the cluster. This may cause inconsistent behavior.

What could be the reason for this? Is this something that could happen when more than 5 threads get triggered by quartz? (Since i hjave specified the threadCound as 5) ?

Thanks in advance for the help.

I’ve looked at a lot of different solutions, and in my humble opinion Aspose is the way to go. Here’s the link: http://aspose.com
