Poor Wormbo.It has the same mercury missiles from the wraith that crashed the server. The monte carlo like algorithm the trajectory calculation does for the artillery can go unstable and crash the server. Then there are the napalm missiles which each individual missiles burns for some time, with fast updates, using up lots of cpu in the process. And the flak missile... the flak can bounce forever sometimes. It's a big pile of bugs.
The Mercuy Missles were all updated by me, not using same ones from Wraith (which are also corrected/fixed years ago), each vehicle gets its own instance of them so there's no conflict...
All that being said, while its not the cleanest code its on several other large maps without crashing notably JY, Dria.
This is a Tek problem... and the Perses has no Voice interactions indicated by the Critical crash message.
Zounds are more problematic than the Perses. They take up quite a bit of memory.
Node sounds shouldn't be an issue... nodes play sounds all the time.
All in all, this error might have been a one time thing, or some left over garbage from previous map.
