Hi Folks,   Thanks for the replies.
What seems to be happening in my case , is when I send a graceful restart to
apache, I get the following messages in the access log


127.0.0.1 [05/Feb/2007:13:35:25 +0000] "GET / HTTP/1.0" 400 284
127.0.0.1 [05/Feb/2007:13:35:25 +0000] "GET / HTTP/1.0" 400 284
127.0.0.1 [05/Feb/2007:13:35:25 +0000] "GET / HTTP/1.0" 400 284
127.0.0.1 [05/Feb/2007:13:35:25 +0000] "GET / HTTP/1.0" 400 284
127.0.0.1 [05/Feb/2007:13:35:25 +0000] "GET / HTTP/1.0" 400 284

I am trying to find the root cause of what cause this request when we do
graceful restart.

I have been digging around for some days but not able to find out which code
is causing this.

Any cluse ?

Thanks & Regards
Devi

Not if BSD accept filters are in place. In this case the kernel waits
until it
sees a HTTP request until it wakes up the process.
And on Linux with TCP_DEFER_ACCEPT enabled you need to sent a least one
byte of data.
