Yes, after you have deleted the file there is little you can do to recover the allocated space apart from killing and restarting the process(es) that have the file open.
As RudiC points out you are better off writing zero size to the logfile eg:
Or
As a long-term solution you should consider using the logrotate daemon to keep your logfile sizes down.
And don't be surprised if that doesn't work.
There are ways for applications to write to log files that create problems with that method. One of them is redirecting stderr/stdout by using ">>" shell redirection.
If those methods are used, filesystem-specific features can come into play.
There's a reason why operating systems provide robust, scalable logging facilities. Scalable logging is not something that can be done reliably without serious work.
So if your app is not well-designed, you may be stuck with "kill the app, clean up the log file, restart the app".

penlogd
PENLOGD(1) General Commands Manual PENLOGD(1)NAME
penlogd - consolidate web server logs
SYNOPSIS
penlogd [-fd] [-j dir] [-l logfile] [-n N] [-p pidfile] [-u user] port
EXAMPLE
penlogd -l /var/log/access_log -p /var/run/penlogd.pid 10000
DESCRIPTION
Penlogd receives log entries from Pen and from each of the web servers. It consolidates the entries by replacing the source addresses in
each entry with the "real" client address and writes the result to stdout or to the file given on the command line. This completely
removes the need for postprocessing with mergelogs, since the logs are already merged.
Pen must be instructed to send its log to penlogd. See HOWTO and pen man page for details.
Sending penlogd a HUP signal will make it close and reopen the logfile, unless it is logging to stdout. Rotate the log like this:
mv access_log access_log.1 kill -HUP `cat <pidfile>`
where <pidfile> is the file containing pen's process id.
Sending penlogd a TERM signal will make it close the log file and exit cleanly.
OPTIONS -d Turn on debugging. The output goes to stderr if we are running in the foreground (see -f) and to syslog (facility user, priority
debug) otherwise.
-f Stay in foreground.
-j dir Run in a chroot environment.
-l logfile
Write output into logfile.
-n N Number of pen log entries to cache (default 1000).
-p pidfile
Write process id into pidfile.
-u user
Run as a different user.
port The UDP port where penlogd receives log entries.
