Thanks for the details! It gave me another perspective on things.

Disk Space? Libraries? Etc..< Sorry, I do not really know. I had one similar, very strange effect on my embedded LINUX, regarding bash: It was necessary for redirect function in bash to work, to have this one: ln -s /proc/self/fd /dev/fd So just my idea about this special squid function having a similar reason. Because as I have seen, squid uses socket connections to communicate with the helper. So just a long shot. It very looks like squids accouting of helpers is disturbed: I see much more than max helpers active after a few hours. And lot of helpers stay alive, when I kill parent process squid. This problem only shows up, in case of having 2 (or more) active requests to 2 helpers (same key: %SRC). Like squid assumes some internal queuing of the 2 requests, but second request is not. So it also could be some type of resource issue: Only one socket conn allowed for squid, second one is silently ignored. This would cause exactly my effect. It must be something very special, as I have a lot of other software running on this embedded LINUX, incl. nginx, rsync. And without the helper, squid ran fine for long time, incl. cache to SSD. configure options: Squid Cache: Version 3.5.22 Service Name: squid configure options: '--target=mipsel-openwrt-linux' '--host=mipsel-openwrt-linux' '--build=x86_64-linux-gnu' '--program-prefix=' '--program-suffix=' '--prefix=/usr' '--exec-prefix=/usr' '--bindir=/usr/bin' '--sbindir=/usr/sbin' '--libexecdir=/usr/lib' '--sysconfdir=/etc' '--datadir=/usr/share' '--localstatedir=/var' '--mandir=/usr/man' '--infodir=/usr/info' '--disable-nls' '--config-cache' '--datadir=/usr/share/squid' '--libexecdir=/usr/lib/squid' '--sysconfdir=/etc/squid' '--enable-shared' '--disable-static' '--disable-icmp' '--enable-delay-pools' '--disable-icap-client' '--enable-kill-parent-hack' '--disable-snmp' '--disable-ecap' '--disable-wccp' '--disable-wccpv2' '--disable-eui' '--disable-htcp' '--disable-ident-lookups' '--enable-auth' '--disable-storeid-rewrite-helpers' '--disable-ipv6' '--enable-ssl' '--enable-ssl-crtd' '--disable-cache-digests' '--enable-linux-netfilter' '--disable-unlinkd' '--disable-x-accelerator-vary' '--disable-translation' '--disable-auto-locale' '--with-dl' '--with-pthreads' '--without-expat' '--without-libxml2' '--without-gnutls' '--without-nettle' '--with-openssl=/etc/openwrt/mw-m96/staging_dir/target-mipsel_24kec+dsp_uClibc-0.9.33.2/usr' '--enable-epoll' '--with-maxfd=4096' '--enable-external-acl-helpers' '--disable-auth-negotiate' '--disable-auth-ntlm' '--disable-auth-digest' '--enable-auth-basic' '--disable-arch-native' '--with-krb5-config=no' '--without-mit-krb5' '--without-libcap' '--without-netfilter-conntrack' 'build_alias=x86_64-linux-gnu' 'host_alias=mipsel-openwrt-linux' 'target_alias=mipsel-openwrt-linux' 'CC=mipsel-openwrt-linux-uclibc-gcc' 'CFLAGS=-Os -pipe -mno-branch-likely -mips32r2 -mtune=24kec -mdsp -fno-caller-saves -fhonour-copts -Wno-error=unused-but-set-variable -Wno-error=unused-result -msoft-float ' 'LDFLAGS=-L/etc/openwrt/mw-m96/staging_dir/target-mipsel_24kec+dsp_uClibc-0.9.33.2/usr/lib -L/etc/openwrt/router/staging_dir/target-mipsel_24kec+dsp_uClibc-0.9.33.2/lib -L/etc/openwrt/router/staging_dir/toolchain-mipsel_24kec+dsp_gcc-4.8-linaro_uClibc-0.9.33.2/usr/lib -L/etc/openwrt/router/staging_dir/toolchain-mipsel_24kec+dsp_gcc-4.8-linaro_uClibc-0.9.33.2/lib ' 'CPPFLAGS=-I/etc/openwrt/router/staging_dir/target-mipsel_24kec+dsp_uClibc-0.9.33.2/usr/include -I/etc/openwrt/router/staging_dir/target-mipsel_24kec+dsp_uClibc-0.9.33.2/include -I/etc/openwrt/router/staging_dir/toolchain-mipsel_24kec+dsp_gcc-4.8-linaro_uClibc-0.9.33.2/usr/include -I/etc/openwrt/router/staging_dir/toolchain-mipsel_24kec+dsp_gcc-4.8-linaro_uClibc-0.9.33.2/include ' 'CXX=mipsel-openwrt-linux-uclibc-g++' 'CXXFLAGS=-Os -pipe -mno-branch-likely -mips32r2 -mtune=24kec -mdsp -fno-caller-saves -fhonour-copts -Wno-error=unused-but-set-variable -Wno-error=unused-result -msoft-float ' 'PKG_CONFIG=/etc/openwrt/router/staging_dir/host/bin/pkg-config' 'PKG_CONFIG_PATH=/etc/openwrt/router/staging_dir/target-mipsel_24kec+dsp_uClibc-0.9.33.2/usr/lib/pkgconfig:/etc/openwrt/router/staging_dir/target-mipsel_24kec+dsp_uClibc-0.9.33.2/usr/share/pkgconfig' 'PKG_CONFIG_LIBDIR=/etc/openwrt/router/staging_dir/target-mipsel_24kec+dsp_uClibc-0.9.33.2/usr/lib/pkgconfig:/etc/openwrt/router/staging_dir/target-mipsel_24kec+dsp_uClibc-0.9.33.2/usr/share/pkgconfig' -- View this message in context: http://squid-web-proxy-cache.1019090.n4.nabble.com/external-acl-type-problem-tp4680203p4680302.html Sent from the Squid - Users mailing list archive at Nabble.com. _______________________________________________ squid-users mailing list squid-users@xxxxxxxxxxxxxxxxxxxxx http://lists.squid-cache.org/listinfo/squid-users _______________________________________________ squid-users mailing list squid-users@xxxxxxxxxxxxxxxxxxxxx http://lists.squid-cache.org/listinfo/squid-users
