Hello.
Running Squid 7.3 on several boxes.
In the last couple of days it has been crashing on one.
Last time I captured this in the logs:
2026/02/05 15:22:10 kid1| WARNING: dns-mime-type ACL is used in
context without an HTTP response. Assuming mismatch.
current master transaction: master72
As the message says The ACL you have named "dns-mime-type" is being
checked when there is no HTTP Response. I assume from the name that it
needs the mime type, which comes from an HTTP Response header.
Squid copes with these by assuming a mis-match or skipping the access rule.
This is a flaw in your security policy which you should fix, maybe minor
or maybe serious - hard to tell without full knowledge of that policy
and reasons for it.
2026/02/05 15:22:10 kid1| FATAL: invalid pct-encoded triplet
exception location: Uri.cc(102) Decode
current master transaction: master72
This is likely bug 5501.
"
The bug affects url_regex and urllogin ACLs. However, not every use of
those ACLs results in a FATAL exit. The exact preconditions are unknown.

I have initiated a backport for the fix to v7.
You can find the patch at <https://github.com/squid-cache/squid/pull/2369>
2026/02/05 15:22:10| Removing PID file (/var/run/squid/squid.pid)
The first two lines are quite common.
I searched for the subsequent messages, which seem to be the interesting
ones, but found nothing.
I'll try to upgrade to 7.4 and possibly get a core dump, but if someone
has any hint in the meantime...
7.4 will not help with this particular issue. Though upgrade is usually
worthwhile anyway.
