Hi, All! I've RedHat Linux 3 Enterprise Edition with Squid (2.5.STABLE7) and Samba (Version 3.0.0-14.3E) installed on C2.4GHz/512Mb/80Gb computer. Squid configured with Windows domain authentication using samba's winbind. All works fine. When server works for 3 or 4 month and I restart samba's services (smbd, nmbd and winbind) domain authentication doesn't work (wbinfo -u shows nothing, squid doesn't authenticate users, so do apache, which is also installed on this server). There are several strings also appears in squid's cache.log [2005/09/08 10:30:01, 1] utils/ntlm_auth.c:manage_squid_request(1042) fgets() failed! dying..... errno=0 (Success) Restarting server computer don't solve this problem. I've found temporary solution. I stop squid, delete all files from squid's cache dir, then run 'squid -Z' command and finally start squid itself. After it all services works for several month... Here is output from df -B M command File system 1M-bloks Used Free Used%Mouted to /dev/sda2 10077 2477 7088 26% / /dev/sda1 198 10 179 5% /boot none 243 0 243 0% /dev/shm /dev/sda5 66008 2328 60328 4% /var Any ideas? Thanks in advance. Fyodor
