Ufdbguard fails reload

Bug
1

Hi, i still have some problem with latest ufdbguard. I think related with https://github.com/NethServer/dev/issues/6323

i can replicate the error executing /etc/cron.daily/update-squidguard-blacklists

ov  6 10:34:51 ns7proxy ufdbguardd: *** Error in `/usr/sbin/ufdbguardd': corrupted size vs. prev_size: 0x00000000016ab7c0 ***

i didn’t have time now to look further, but a quick and dirty solution was to change the latest pkill from SIGHUP to SiGKILL
i’ll do some other test in the afternoon to see if i can replicate the problem also on other installation…

just an update here as the issue is closed… I did some other tests:

  • on a low traffic installation: nethserver-squidguard-2.0.6-1 seems to solve the problem (both with reload and with blacklist update ufdb crashes but then it restart)
  • on an installation with lot more traffic with nethserver-squidguard-2.0.6-1: both the reload and the blacklist update crash ufdbguard and it doesn’t restart.
    updating blacklists with sigkill it freezes but then restarts
  • on the installation with more traffic with nethserver-squidguard-2.0.6-1: I updated ufdbguard from epel testing (ufdbGuard-1.35.3-1.el7) and now both the reload of ufdbguard and the blacklist update with sighup seem to work correctly :raised_hands:

so i think i have some hour to play with 7.9 :nerd_face:
