if you rebooted the CSS then it is too late to help you. [unless the problem is still there].

Next time, capture 'script play show_tech' and a sniffer trace of the keepalive traffic.

Try to see if different type of keepalive work and if you can ping the servers from the CSS.

Regards,

Gilles.

Gilles,

I don´t know if different keepalive work, just I try to make a ping to web servers and working fine.

The scenario is that I have 3 content balancing web server and 3 content balancing NetCache but when add the 4th, after many hours appears the problem that I mentioned.

Gilles,

Recently its happen again. I send to you the script of show_tech.

FLOWMGR-6: <010> FM_Tcp: Handling generic FMTCP flow Re-Transmit ERROR

Hi Guilles,

Could you see the "showtech"...? What do you think..?

Thanks for your help.

Guillermo,

I checked the show tech and there is no info there indicating a problem except a huge number of servers down.

Could you capture a sniffer trace between the CSS and some servers to see what is going on.

Try to capture on a switch adjacent to the CSS.

Thanks,

Gilles.
