[pmwiki-users] pmwiki hangs when editing

I have been managing a pmwiki installation for a couple of years now, and generally we have no problems, but we have come across a handful of instances over time when on adding some text to a page, the server does not respond when the edit is submitted either by clicking the save button or just a preview. This is then fully reproducible with the same text if I keep trying to submit the edit, but I can usually narrow it down to a particular word with the new text that causes the problem - if I remove that word, or replace it with a different word, then I can then submit the edit without a problem. However there doesn't seem to be anything special about these bits of text that lead to the problem nor can I discern a pattern to the text that causes the hang among the few cases where it has happened. In fact, the same text might already occur elsewhere on that page without an issue.

So firstly, does anybody have any idea what might be going on here.

But assuming not, could you suggest a route I might take in trying to track down what is happening on the server in these instances = where in the pmwiki code should I start looking to perhaps add some tracing statements in an attempt to debug this?
