So it is not just Hudson, and you want a full reboot?
If it is Linux, as root, record the output of:

ls -l /proc/*/fd
ls -efwww

See the per-process open file descriptors limit:
ulimit -n

The limit includes children, so exec'ed svn subprocesses will be 
affected by an fd leak in the parent process.

I think it unlikely that this is system level issue, as since 2.2 or 2.4 
(?) this is dynamic and large. for example:
cat /proc/sys/fs/file-max
389262
Handles in use:
cat /proc/sys/fs/file-nr
6208    0       389262

Unless the system is near its soft limit, you should be able to resolve 
the issue by restarting tomcat.

Kind regards,
Ben.
