Sounds like you are not getting the 'too many open files' error
anymore.  Could you confirm it?

Do you get OutOfMemoryError in the end or is it just working fine?  I
do see saw-toothed patterns in the memory graph, but I never got an
exception so far.  If the connection rate is high, GC will be busy,
but I'm not sure it will slow down the application seriously.
Additional information is appreciated.

Thanks
