There is no way for you to find out what that means; it’s a link to an internal location in a diagnostic file. The file can be used by Apple to diagnose problems by feeding it into a log analyzer, but it’s not something that mere mortals can interpret. Focus on the symptom that you are seeing; if you contact Apple support using the link at the top of this page or visit a genius bar Apple can run a remote diagnostic to try to identify the problem.
If you are seeing this problem on multiple devices, do you have any enterprise apps installed on the phone specific to your company? If so, most likely it is caused by a bug in the app.
