Re: SOlaris 2.6, squid 1.1.21 poll() ERESTART errors

Hmm.
        OK - patch appears not to work, however I may be starting squid wrong
(after all these years!)
        If I start squid from a TTY eg: squid &, then any other process in
that group, the poll gets sent to squid and it still doesn't handle it
correctly.
        Can anyone tell me why squid doesn't disassociate itself from the
process group?
        Also, the squid FAQ lists several ways to start squid - which one
should be used with this problem, since I can find no docs on the -sYC
startup options?
