Hello Alex, Thank you for the reply and the bug report link. Totaly forgot to check the bugzilla, sorry for that. I did read it and that exact what it is. I also can confirm that the assertion only happens with the logrotate. Squid does not crash so that looks all ok to me, i just dont like the messages in my logs. So for now i changed the logrotate, which eliminated the message. >From the default debian logrotate, and yes, i would preffer squid -k rotate also. But for now, i'll restart. I changed logrotate to: prerotate test ! -x /usr/sbin/sarg-reports || /usr/sbin/sarg-reports daily Endscript postrotate if [ -d /run/systemd/system ] && command systemctl >/dev/null 2>&1 && systemctl is-active --quiet squid.service; then systemctl restart squid.service elif [ -f /var/run/squid.pid ]; then test ! -e /var/run/squid.pid || test ! -x /usr/sbin/squid || /usr/sbin/squid -k rotate fi endscript Best regards, Louis > -----Oorspronkelijk bericht----- > Van: Alex Rousskov [mailto:rousskov@xxxxxxxxxxxxxxxxxxxxxxx] > Verzonden: donderdag 2 augustus 2018 17:43 > Aan: L.P.H. van Belle; squid-users@xxxxxxxxxxxxxxx > Onderwerp: Re: assertion failed > > On 08/02/2018 07:46 AM, L.P.H. van Belle wrote: > > > If i google for "assertion failed: comm.cc:428: "!isOpen(conn->fd)" > > i get only 3 hits, is someone knows what this is, because i > cant figure > > this out. > > When facing an assertion, one should check Squid bugzilla: > https://bugs.squid-cache.org/show_bug.cgi?id=4796 > > Alex. > > > 2018/08/02 06:25:01 kid1| storeDirWriteCleanLogs: Starting... > > 2018/08/02 06:25:01 kid1| logfileRotate: > daemon:/var/log/squid/access.log > > 2018/08/02 06:25:01 kid1| logfileRotate: > daemon:/var/log/squid/access.log > > 2018/08/02 06:25:01 kid1| assertion failed: comm.cc:428: > "!isOpen(conn->fd)" > > > _______________________________________________ squid-users mailing list squid-users@xxxxxxxxxxxxxxxxxxxxx http://lists.squid-cache.org/listinfo/squid-users
