SquidGuard error in processing big blacklist

[moscard]

Behaviour :
SquidGuard do not filter end of a big blacklist
By instance, it blocks correctly pornhub.com but let free access to xvideo.com even if it is in the blacklist.

Cause:

• The RAMdisk size for /tmp/squidGuard is too small.
• Strangely SquidGurad do not display nor log any error.
• The only found error is on system log:
  Jul 2 23:05:07 kernel pid 5419 (squidGuard), uid 0 inumber 9742 on /tmp/squidGuard: filesystem full

Fix (workaround) :
At the line 1985 of the /usr/local/pkg/squidguard_configurator.inc script file, I had to change " $ramsize = 300;" by " $ramsize = 600;" doubling the ramdisk size.

#*****************************************************************************
# RAMDisk
#     Temp ramdisk for quickly DB update
# *****************************************************************************
function squidguard_ramdisk($enable)
{
    $ramsize = 300;

    # delete old squidguard ramdisk
    if (file_exists("/dev/md15")) {
        mwexec("/sbin/umount -f " . SQUIDGUARD_TMP);
        mwexec("sleep 1");
        mwexec("/sbin/mdconfig -d -u 15");
    }
...

Is that possible to fix this on future releases or give an option on SquidGuard GUI to provide the RAMdisk size ?
