An upstream response is buffered to a temporary file

[Ilan Berkner]

Thanks,

I increased the fastcgi_buffers as follows:

fastcgi_buffers 256 4k;

and that took care of this problem.

Another problem I'm trying to deal with is:

netstat -an|awk '/tcp/ {print $6}'|sort|uniq -c
     12 CLOSING
   1176 ESTABLISHED
     58 FIN_WAIT1
    218 FIN_WAIT2
     23 LAST_ACK
     43 LISTEN
     91 SYN_RECV
   3606 TIME_WAIT

I'm trying to understand why there are so many connections in TIME_WAIT
status.  Any ideas on how to research this issue?
