AW: AW: [squid-users] Squid File Descriptor Size

do you have a "high volume" squid?
we also use aufs with our squids (on suse linux 7.3) without major problems.
aufs should be a bit buggy - see squid.conf comments. but we don't have any
segmentation faults. we use configure with the following options:

./configure --with-aio-threads=32 \
             --with-pthreads \
             --enable-storeio=ufs,aufs \
             --disable-ident-lookups \
             --prefix=/users/www/squid \
             --enable-err-language=German \
             --enable-underscores \
             --disable-internal-dns \
             --enable-gnuregex

configure options for aufs:

 --enable-async-io[=N_THREADS]
                         Shorthand for
                         --with-aio-threads=N_THREADS
                         --with-pthreads
                         --enable-storeio=ufs,aufs"

maybe you can increase the number of threads, default is 5 (i think)
