Re: [Cobertura-devel] Cobertura Limits

[Steven C. <ste...@re...>]

I am currently using trunk,  I have yet to try your changes.
The failure is occurring during 'business', I also notice it is doing 
flushes correctly, and it's producing results. The cobertura.ser file 
gets to about 2mb before the crash occurs. I am flushing after every 
test with the assumption garbage collection will clean up everything, 
and garbage collection will shrink the array size. I want to refrain 
from doing explicit GC calls unless absolutely necessary.
