Subject Re: Trinidad jar - "too many open files" Exception
Date Tue, 11 Sep 2007 11:45:39 GMT
Hi,

we had something, mentioned with a SNAPSHOT of 1.0.2.
Adam fixed something related to this. My guess is, you are using the
release, isn't it ?

Peter, is this still an issue for you guys ?

Thanks!
Matthias
