Hey Cris,



What sort of connection rates are you using? And what=92s the length of eac=
h
connection?



How=92s the BigIP setup? What profiles are you using?



I=92m wondering if there=92s issues with lots of half-open/ queued handshak=
es
that the BigIP is throwing away? Or if the BigIP thinks it=92s being DoS=92=
d.



4.6 was such a long time ago....  I think those brain cells were fried some
time back... ;-)



Cheers,



Andrew

Hi list,

Im running a benchmark against a pool of 4 apaches behing a VIP.

When i run the test, generating 50.000 connections against each apache,
works great.

When I run the test, generating 50.000 connections against the VIP i get:

Completed 5000 requests
Completed 10000 requests
apr_socket_recv: Connection reset by peer (104)
Total of 11469 requests completed

Looks like F5 resets connections after 10.000 connections.

Please note I am using keepalive on the benchmark test.

Any hint would be greatly appreciated.

Thanks
Cris
