Hello,
I have been facing few squid issues lately. we are about 40 users mostly linux, some mac and some windows system.
squid has become very slow for some reason. we can check that by bypassing squid and opening same urls. Second thing we are seeing swap mismatch errors and only solution we found is to remove swap file and use squid -z that will make things work for a day. other than that there are other errors in squid log too.
/var/cache/squid directory has became around 80 gb.
Here is our squid version and conf file
Squid Cache: Version 3.5.23
Service Name: squid
configure options: '--prefix=/usr' '--localstatedir=/var/squid' '--libexecdir=/lib/squid' '--srcdir=.' '--datadir=/share/squid' '--sysconfdir=/etc/squid' '--with-default-user=proxy' '--with-logdir=/var/log/squid' '--with-pidfile=/var/run/squid.pid' '--with-openssl' '--enable-ssl-crtd' '--enable-inline' '--disable-arch-native' '--enable-async-io=8' '--enable-storeio=ufs,aufs,diskd,rock' '--enable-removal-policies=lru,heap' '--enable-delay-pools' '--enable-follow-x-forwarded-for' '--enable-url-rewrite-helpers=fake' '--enable-ecap' '--enable-arp-acl' '--disable-translation'
Squid.conf file
Squid error log
if you see error log file you can see Error negotiating SSL errors and Ignoring malformed cache entry errors frequently.
squid access also have lot of entries like,
1488621158.416 1316 192.168.1.51 TAG_NONE/200 0 CONNECT 35.154.95.34:443 - ORIGINAL_DST/35.154.95.34 -
1488621158.416 1315 192.168.1.51 TAG_NONE/200 0 CONNECT 35.154.95.34:443 - ORIGINAL_DST/35.154.95.34
which i believe https requests which have certificate issues. this has became growing for mac machines.
Anybody else have similar issues?
We are not sure weather it was the 3.5.23 upgrade or adding Mac systems to our network is causing these issues. but squid has certainly become slow for lots of people to the point we have to bypass them.
Thank you very much for reading through the post. Let me know if you find any issues with our config or anything that can help us figuring out whats the issue.
Have a good day.
