Hi juraj, Added that line and didn't help :(. This is what happens: 1) Squids were configured without sibling. 2) Configured sibling on each squid as showed before (4 cache_peer lines per squid, total 5 squids). 3) Reloaded (not restarted) squid. Sibling started working.... After a while (~20 secs). Stopped working. 4) Changed some settings (disable siblings, reloaded, enabled siblings, reloaded) and no ICP requests were sent. 5) Restarted Squid and sibling started working again for ~20 secs again. So every change I make I have to restart squid :( About if I see SIBLING_HITs on my access.log, yes, for those 20 secs sibling works. I see SIBLING_HITs :( Thank you!
