XF 1.3 Fatal Error: Maximum execution time

[Mouth]

Getting the following error in the Server Error Log, for a single/specific thread only, and different pages for the thread ...

1. Fatal Error: Maximum execution time of 300 seconds exceeded10 minutes ago - library/XenForo/Template/Abstract.php:591
2. Fatal Error: Maximum execution time of 300 seconds exceeded14 minutes ago - library/XenForo/Template/Public.php:242

Any ideas on how I can diagnose and resolve?

Strangely, both of those seem to be related to requiring external values. It certainly looks like there may be an infinite loop somewhere.

I would definitely confirm on a default style and with all add-ons disabled. If you have an opcode cache, try clearing it (or restarting the web server); we have seen some instances where the code being executed didn't seem to fit with the code as written.
