Hello,

i have the problem that after a couple of days Hudson hangs, only throwing "too
many open files" exceptions again and again. lsof shows that there are several
thousand tmp-files in
/home/hudson/.hudson/jobs/QIS_HEAD/builds/2009-05-29_07-11-46/workspace-files/7f16be5b.tmp

They contain this stacktrace:

Can't copy file from slave to master:
slave=/home/hudson/hudson/workspace/QIS_HEAD/qisserver/WEB-INF/src/generated/de/his/appserver/service/dto/gen/HisbezeichnerDtoFactory.java,
master=/home/hudson/.hudson/jobs/QIS_HEAD/builds/2009-05-29_07-11-46/workspace-files/ff810f24.tmp

Hudson is running as a master withou any executers and one slave with two executers.
