case of the missing template?

Jun 13, 2012 6:20 AM

This one drives me nuts. Every few days, I will get the following error on a particular action of a ColdFusion app:

 

(class: cfact_getXYZ2ecfm174795703, method: runPage signature: ()Ljava/lang/Object;) Incompatible object argument for function call

 

It seems to happen at a lower level than a typical ColdFusion error because my normal cftry/cfcatch doesn't get triggered from what I can tell.

 

The template listed in the class is always the same template (the act_getXYZ…) even though this action includes several templates and CFC calls before and after that one.

 

When I check the server, the template (.cfm file) is there.  It hasn't gone anywhere nor gotten overwritten.

 

Here's the kicker. All I have to do is make a change to the .cfm file, re-save, and it works again.  And by change, I mean add and remove a space, or something else trivial.

 

Here is another kicker. This template is on three servers in a load-balanced environment, and it happens on every one of them.   

 

Web searches have come up empty.  Any ideas?

    Another clue to this that might help solve the mystery:  If this situation happens and I clear the template cache, it works again.

     

    So, what would cause this?  Why would I have to clear a cache regularly for this one template to get re-created?   Any ideas?

    The compiled class is getting corrupted in memory, so either touching the file or clearing the class from cache will force a recompile.  So that explains that side of things.

     

    As to how the thing is getting corrupted in the first place?  No idea.

     

    What is idiosyncratic about act_getXYZ.cfm?  What's it's code?

    Yep, there's the mystery.

     

    The code is looping through a query that was created from an upstream template, creating HTML, and saving it with cfsavecontent.  At runtime, the query would be < 100 rows with perhaps 1K per row at the very most.  The size of the code is 66 lines.
