Under load, StoRM 1.11.1 exceeds in number of threads created.
It hits the default number of threads limit of 1024 in /etc/security/limits.conf
After increasing that value, in less than 24h, over 8000 threads have been created.
Also, performance is poor - fts logs show an 80s wait in "Src Prep Duration". Probably because of this, lcg-gt and lcg-cp commands time out.
