My application server, SJSAS 9.0 b48 with Apache in front, hang up sometime and nothing is available anymore.
After some time (10-30min) or after an restart everything works like before.
Did lot of discussion with admin of my ISP and he told me, that he increase the maximum open file size.
But problem still exist and is not reproducible (for me) - happens on different hours/days.
Here is depending the trace from logs:
