Hello, We recently upgraded our Squid server from a Sun Ultra60 running Solaris 2.8 to a Sun V240 running Solaris 2.9. I also took the opportunity to upgrade Squid from 2.5STABLE3 to 2.5STABLE7. Now our streaming video (Real Media) no longer works (it hangs). The old proxy is still around as a standby and it still works, but we are retiring that server so keeping it is not an option. I used the same conf file (after determining what, if any, new options were in the new squid.conf.default). In fact the only changes the "diff" command shows are the size and number of the cache dirs. So next I checked the compile options, and the only diffs are the STABLE7 version was compiled with aufs-threads and Spanish while the STABLE3 has asyn-io. All other options are the same. So I then checked the ChangeLog, Release Notes, the Bug database, and the archives for the mailing list and found nothing. But I am not exactly sure how to characterize the problem so I may have just not searched for the right terms. I would have assumed a change to our network or something but nothing has changed recently except for the upgrade. The new Squid server is, other than this, proxying fine for 1500 people. Does anyone have any ideas as to what changes in Squid would have broken RealMedia flows? Again, I have two servers that are configured the same. The STABLE3 works with RealVideo and the STABLE7 does not. I am humbly requesting either help fixing this or pointers to how to research the problem. thanks Adam BINARY DIFFS ARE TRIVIAL: NEW: Squid Cache: Version 2.5.STABLE7 configure options: --prefix=/usr/local/squid-2.5.STABLE7 --enable-dlmalloc --enable-aufs-threads --with-pthreads --enable-storeio=aufs,ufs --enable-removal-policies=heap,lru --enable-delay-pools --disable-icmp --enable-cachemgr-hostname=aocproxy --enable-snmp --disable-ident-lookups '--enable-err-languages=English Spanish' OLD: Squid Cache: Version 2.5.STABLE3 configure options: --prefix=/usr/local/squid-2.5.STABLE3 --enable-dlmalloc --enable-async-io --enable-storeio=aufs,diskd,ufs --enable-removal-policies=heap,lru --enable-delay-pools --disable-icmp --enable-cachemgr-hostname=aocproxy --enable-snmp --disable-ident-lookups --with-pthreads Squid.conf diffs: OLD cache_dir aufs /cache 19000 16 256 OLD cache_dir aufs /cache2 19000 16 256 NEW cache_dir aufs /cache 7256 16 256 NEW cache_dir aufs /cache2 6800 16 256 NEW cache_dir aufs /cache3 6800 16 256
