Web Tools "Thread List"

[Steve <st...@neobits.com>]

Recently moved an ofbiz installation from one machine to another  
faster machine. Lots of other software was updated since the new  
Centos machine was installed from scratch, so, OS, tools, etc are all  
what Centos calls current. Using openjdk Java.

When looking at the web tools screens in ofbiz, specifically, the  
thread list screen, I see 5 service engine threads. They all say  
running, and, don't ever seem to not say running. I don't see any  
logged messages, but, don't recall this happening before. Service  
running is sendGenericNotificationEmail

Email is the same as the old machine, It sends via the provider. Some  
emails send fine, like the ones for user registration. Other emails,  
like order confirmation, are never sent. I see them in the running  
threads also.

Not sure what is going on, but, I don't think this is normal behavior?  
What would cause the services to keep a running status with no  
messages logged? Any thoughts on where to look?
