One 5 minute interval is the length of the buckets in which MSU consumption is gathered to calculate the 4 hour running average of the MSU consumption. However, I can't think of any action based on this that would generate a 'hang' every interval.
What is your SMF recording interval? And what is your setting of DDCONS? It was famous in the past for hanging the system in order to produce SMF records.

We have a customer with a CICS transaction hang problem that happens intermittently at high load times. We've been able to verify that it's making it out of CICS, doing a PC off to our server. Things clear up eventually; we have various diagnostics in our server that look like things are ok, but we're seeing it after the fact, which of course doesn't prove much. One possibility is that WLM is throttling our server. The hangs *seem* to happen at five-minute intervals. Doing some Googling suggests that WLM does *something* on 5-minute boundaries. Does this suggest anything to anyone? Like, does WLM throttling occur on those 5-minute boundaries? Yes, I'm Easter Egging. Will hopefully be able to get some real information tomorrow when the problem is occurring, but in the meantime, some pointers would be useful. And also yes, I'm trying to grok some WLM books! Having an eye infection that's forcing me to read with one eye isn't helping...
