If you are using eqassemble at the head of your megamodule (assocation/location), make absolutely certain that your computer's system clock is sync'ed to UTC properly or the timer count down in eqassemble, if you use the SinceOrigin flag will get you. You will start seeing degraded performance in your megamodule if the clock drifts significantly....ask me how I found this out!!! It happened on a windows system, the OS magically changed some policy in the update of clocks and suddenly the computer was no longer updating itself using the regular system tools that do that. Thanks Windows!!!
Note you need to keep the clock relatively synced to UTC in order for carlsubtrig to work properly too (many want to fix that aspect, but its a daunting amount of unwinding). I just never considered that this new megamodule also would suffer the same issue using this switch....it makes perfect sense after the fact.
Hope this helps you in your Earthworm configurations.
