Hi there All! I use Squid 2.6 STABLE5 in our intranet (about 150-200 permanent users) with NTLM users authentication via SAMBA ntlm_auth external helper. All works good. But I can see some wornings in squid cache.log: 2006/11/28 18:43:53| comm_accept: FD 74: (233) No buffer space available 2006/11/28 18:43:53| httpAccept: FD 74: accept failure: (233) No buffer space available 2006/11/28 18:44:06| comm_accept: FD 74: (233) No buffer space available 2006/11/28 18:44:06| httpAccept: FD 74: accept failure: (233) No buffer space available ... And so on... about 2-3 per minutes.
This indicates a kernel resource problem. You probably need to increase network buffers. But I am not a wizzard on HP-UX. On some UNIX-es : # netstat -mb may provide more info. M.
