Hello,
I am running squid v2.2 stable 4 on a solaris 2.6 (not patched for the
moment) 128Mo. Since Yesterday, i experience some troubles...a lot of
complaints from clients !
I posted a similar problem to the list : the response was "Not enough
memory" but it a bit different.
I rebuild SQUID with these options :
./configure --prefix=/tools_1/squid2-2-S4 --enable-icmp --enable-snmp
--enable-async-io --enable-delay-pools --enable-err-language=French ...
hoping that async-io would have helped me (?)
Today, i have a ton of this messages in the cache.log :
WARNING: newer swaplog entry for fileno XXXXX
After about 30 mn squid gets *very* slow ...100 bytes/sec (and my phone
ring ;-)), even for a cached page like www.altavista.com ! ... the box
gets very slow too.
I could not find where the problem is !
I give you all information i have .. if someone can help ?
