I think will just store more objects in RAM. Agreed. But it should also depend upon # reply_body_max_size 0 #read_ahead_gap Setting reply_body_max_size 100 MB should create some safety net. -- View this message in context: http://squid-web-proxy-cache.1019090.n4.nabble.com/high-memory-usage-squid-3-2-0-tp4659422p4659441.html Sent from the Squid - Users mailing list archive at Nabble.com.

Amen to that. It got A LOT better. Interesting. Any facts available about mem leaks in 2.7 final, at least ? I am still using it, not recognizing a leak. Which might be caused to non-default configs only, though. -- View this message in context: http://squid-web-proxy-cache.1019090.n4.nabble.com/high-memory-usage-squid-3-2-0-tp4659422p4659446.html Sent from the Squid - Users mailing list archive at Nabble.com.

Amen to that. It got A LOT better. FWIW, my squid 3.1.6 memory usage started to grow indefinitely when I set cache_mem to 1024 MB (however it works well with the default value of 256 MB, which is fine for my current needs). -- Marcello Romani
[squid-users] Re: high memory usage (squid 3.2.0)
What currently seems to happen is that cache_mem is completely ignored and squid is trying to shove up as many objects into my ram as possible, Not exactly. You might be a victim of max_object_size, as I mentionead already above. squid will store a 500MB video temporarily in mem, unles you put some cap on that. Look at access.log, whether you can find such large objects. -- View this message in context: http://squid-web-proxy-cache.1019090.n4.nabble.com/high-memory-usage-squid-3-2-0-tp4659422p4659468.html Sent from the Squid - Users mailing list archive at Nabble.com.
