Corona688 is right here. You will need to force the process to close and reopen the file.
When you redirect output onto the existing file (>logfile or cat /dev/null >logfile) you are causing the file to be unlinked from the filesystem, but if any processes still have an open file descriptor to the file, the disk space is not released and the process will continue to see the file that it has been using all along. This is why you see an empty file in the file system (reported by ls) but the space is still used (reported by du/df) and the application still has issues.

log::dispatch::array
Log::Dispatch::Array(3pm) User Contributed Perl Documentation Log::Dispatch::Array(3pm)
NAME
Log::Dispatch::Array - log events to an array (reference)
VERSION
version 1.001
SYNOPSIS
use Log::Dispatch;
use Log::Dispatch::Array;
my $log = Log::Dispatch->new;
my $target = [];
$log->add(Log::Dispatch::Array->new(
name => 'text_table',
min_level => 'debug',
array => $target,
));
$log->warn($_) for @events;
# now $target refers to an array of events
DESCRIPTION
This provides a Log::Dispatch log output system that appends logged events to an array reference. This is probably only useful for testing
the logging of your code.
METHODS
"new"
my $table_log = Log::Dispatch::Array->new(\%arg);
This method constructs a new Log::Dispatch::Array output object. Valid arguments are:
array - a reference to an array to append to; defaults to an attr on
$table_log
array
This method returns a reference to the array to which logging is being performed.
log_message
This is the method which performs the actual logging, as detailed by Log::Dispatch::Output.
