Strange persist behaviour

Hi Deb,

The original problem was some odd delays/hanging at the squid proxy. I don't think it has any bearing on the persistence problem though.

There's nothing in the logs that I can see, although I am not sure what you meant by the LTM log (I'm looking at local traffic logs in the F5 web interface). There is only gateway_icmp monitoring on the pools at the moment.

I did notice something else odd. This is the persistence table data under pools->squid-proxy-pool->statistics.

   
 Persistence value  Persistence Mode         Virtual Server    Pool              Pool Member       Age   
 172.22.20.220      Source Address Affinity  catchall-virtual  squid-proxy-pool  172.22.21.249:80  4817 seconds     
 172.22.20.220      Source Address Affinity  catchall-virtual  squid-proxy-pool  172.22.21.249:80  1217 seconds     
 172.22.20.228      Source Address Affinity  catchall-virtual  squid-proxy-pool  172.22.21.250:80  731 seconds     
 172.22.20.228      Source Address Affinity  catchall-virtual  squid-proxy-pool  172.22.21.249:80  731 seconds     
 

As you can see, there are two entries for each source IP address. Is it possible that multiple requests arrive simultaneously and are round robin load balanced over the pool, with each request causing an entry in the persistence tables. If so, how do I avoid that? If not, does anyone have an idea what's going on.

Cheers

Andy
