Hi,

After I updated the squid to the 0.4.44_36 version it started to crash and show the same message inside the cache.log file.

I may be wrong, but I saw a correlation between IP 13.224.211.126 (Amazon) and the problem. So, I bypassed this network from the proxy to see if the problem can be fixed.

pfsense: 2.4.5-RELEASE-p1
squid: 0.4.44_36

@volnei hey what made to think, that amazon IP is the culprit?

[Volnei]

So ... as I said, I'm not sure about that. It was more due to the coincidence in access times.
for example:
2021/01/12 13:46:38 kid1 | assertion failed: http.cc:1533: "! Comm :: MonitorsRead (serverConnection-> fd)"
[Tue Jan 12 13:46:38 2021] .682 475 10.15.31.22 NONE / 200 0 CONNECT 13.224.211.105:443 - ORIGINAL_DST / 13.224.211.105 -

When I bypass the proxy network, the problem no longer occurred.

@volnei I have the same problem. The problem, even if it was solved, surfaced again in the latest squid versions 0.4.44_35 - 0.4.44_36.

@a18g3 could you test it on the latest pfSense 2.5 snapshot?
it uses squid 4.13

[gko]

This is a known bug of squid and has been fixed since version 4.11 according to this.
https://redmine.pfsense.org/issues/10608

If someone can make a guide on how to update to the latest port of squid 4.13 using pfsense 2.4.5 p1 it would be really appreciated.

Before yesterday squid stop at once
2021/01/20 15:41:57 kid1| assertion failed: http.cc:1533: "!Comm::MonitorsRead(serverConnection->fd)"
Yesterday twice stop working.
2021/01/21 14:51:33 kid1| assertion failed: http.cc:1533: "!Comm::MonitorsRead(serverConnection->fd)"
I with stability press "Clear cache" button every day - is sad. Yesterday night i have updated to devel 2.5 version with squid-4.13. Will see how it will work.

[Volnei]

Hi,
Please remove the SOLVED flag for this problem as it has not been resolved.
I opened a new ticket in squid's bugzilla: Bug 5101 - assertion failed: http.cc:1533:
"!Comm::MonitorsRead(serverConnection->fd)" (edit)

Thank you.

[viberua]

With devel 2.5 version problem is solved.

[Volnei]

Ok.
I understand.
But unfortunately I've to use only the "stable" version of the production environment.

Anyway, I appreciate the information.

I wish Netgate would understand how serious this issue is. This forced me to buy 20 new fortigates in December The squid functionality is absolutely essential in todays network environment. I have 20 netgate routers on the sheld now not in use :-(

[tobyswe]

And why is this thread still considered as solved ??? Unfortunately i lost a lot of godwill in my organisation because i hade really promoted Pfsense as a good router solution. In the end there was no choice. I had to get rid of them. I could not have my team monitoring squid process 24 hours a day and restart it all the time. Really terrible.

[viktor_g]

Squid version in pfSense 2.5/21.02 is 4.13:

[2.5.0-RELEASE][root@xxx]/root: pkg info squid

Name           : squid
Version        : 4.13
