Hi, I'm trying to track down why I'm getting cflock timeouts when I reinit my MG app. I'm running MG 3.1.299, ColdSpring 1.2, on CF10.

We recently added a new service to our ColdSpring configuration. Now whenever I reinit my app (90% of the time) I get an exception:

A timeout occurred while attempting to lock bf_2FF19388-5056-8039-313716B9BA80BB20.bean_SessionService.
C:\inetpub\wwwroot\coldspring\beans\DefaultXmlBeanFactory.cfc (756)
C:\inetpub\wwwroot\coldspring\beans\DefaultXmlBeanFactory.cfc (632)
C:\inetpub\wwwroot\ModelGlue\gesture\externaladapters\ioc\ColdSpringAdapter.cfc (46)
C:\inetpub\wwwroot\ModelGlue\gesture\ModelGlue.cfc (228)
C:\inetpub\wwwroot\navpointcx\controller\Controller.cfc (19)

I've added debugging code to ColdSpring to log when beans are created and inited. They all take < 10ms. The "init" method on this new service just sets 2 config values and then returns "this". There's nothing in here that I can see that would be slowing things down.

I could see how other requests might get a lock timeout while they wait for me to reinit the framework, but I don't understand why I am getting a lock timeout since I'm the one reinitalizing.

How is another request creating beans and blocking me? Shouldn't only my request be the one creating beans?

I only get the timeout in production so it's hard to troubleshoot.

Thanks for any help.

BTW, the start of that stack trace there, line 19 in the controller is this:
<cfset var SecurityService = getModelGlue().getBean("SecurityService") />

I think it's related to another change we made at the same time - which is accessing the SecurityService from Application.cfc.

It might be a conflicting lock in your code.

>From your description, it only happens in production, meaning it happens when concurrent users do the same thing, or try to use the same shared resource.
