[squid-users] squid-2.5.stable9 aufs issue

Hello,

we are working with a production squid-2.5.stable9 on a Red Hat
Enterprise Linux AS release 4 (Nahant), redhat prepared 2.6.9-5 kernel,
and are getting the following messages, aufs related, on cache.log..

FATAL: Write failure -- check your disk space and cache.log
Squid Cache (Version 2.5.STABLE9): Terminated abnormally.

Configuration for squid is the following..

./configure \
--prefix=/usr/local/squid-2.5.STABLE9 \
--disable-wccp \
--enable-ssl \
--with-openssl=/usr/local/ssl \
--enable-cache-digests \
--enable-default-err-language=Spanish \
--enable-err-languages="Spanish English" \
--disable-ident-lookups \
--disable-hostname-checks \
--enable-underscores \
--enable-async-io

We had prepared another pool /cache2 for cache writing with ufs, and
moved squid.conf configuration from

cache_dir aufs /cache 20480 16 256
#cache_dir ufs /cache2 20480 16 256

#cache_dir aufs /cache 20480 16 256
cache_dir ufs /cache2 20480 16 256

Everything is working well now.. Any idea for the error above? Should I
report a bug o something?..

Thank you in advanced for your help..
