Remember this anyone? Well, the problem is back and I am not any
smarter about it than I was last year.
Basically, I "solved" the issue below only on one single machine by
using jdk-1.5.0_07 instead of the gnu jdk. That was good enough then,
however, now I need to be able to compile our application (> 250
tables) on another machine and I just cannot figure out how to get
rid of the "Too many open files" error. I have tried everything I can
think of (jdk versions, ant versions, command line options for
java.vm.info and java.class.path since I saw some differences there),
alas, to no avail! Everything compiles fine on Windows and OS X, just
not on linux. It's not the descriptor limit as that is the same on
all boxes (1024) except for OS X where it is 256 only.
Any help/pointers would be greatly appreciated. I would be happy to
share the ant debug output with anyone willing to help.
thanks,
h.

When running the torque generator for a good-sized turbine project,
we run into the system limit of 1024 open file descriptors with the
stack trace as below, which occurs in the torque-data-model target.
lsof indicates that the process is keeping all {Base}Foo{Peer} and
associated map classes open. We are still using the ant build based
on the turbine TDK, so the previously suggested solutions do not
seem to be applicable for us. Library versions are torque-gen-3.2
and velocity-1.4. Any advise would be greatly appreciated. We would
prefer to solve this without changing the OS limits. OS is FC4,
kernel 2.6.15-1.1831_FC4smp. Java is gij version 4.0.2.
thanks,

PS: Sorry for the cross-post (since it seems a Velocity problem, I
may even have to take it there).
