Try configuring 'server no-slow-start' on the box and try again.<br><br>-Dave<br></div><div style="font-family: times new roman,new york,times,serif; font-size: 12pt;"><br><div style="font-family: arial,helvetica,sans-serif; font-size: 13px;">----- Original Message ----<br>From: arne van theemsche <arnevt@gmail.com><br>To: foundry-nsp@puck.nether.net<br>Sent: Friday, August 29, 2008 2:31:24 AM<br>Subject: [f-nsp] bucket reassignment on failed health-check<br><br>
Dear group<br><br>this is the 2nd problem we have on our foundry setup<br><br>we are using a VIP with persistent hash buckets (IP gets translated to <br>value between 1-255, and value is assigned to real server)<br><br>each real server has a health-check policy assigned to it.<br><br>Meaning is, that if a health check fails (not only if the server or port <br>fails) the buckets assigned to the real server get removed (this is ok)<br>if a healthcheck returns to a true value (server can be attached again <br>to the VIP) we want the existing buckets to be reassigned to get a equal <br>load. This is not done. Acutally notthing is done, we have to manually <br>do a "port http clear-persist-hash-buckets"<br><br>the default behaviour is to reassign on change, but am I missing something?<br><br>relevant info below<br><br><br><br>server l7-hashing-bucket-reassign<br>server persist-hash-threshold 80 ### high number, are actually 12 <br>servers
