Hi All,
I have a limitation for writev and readv to 52KB.
I was getting error for writev, therefore I changed THRESHOLD_MAX_BUFFER to
42KB. After that I was not getting any error.
Now in GET request of large file, I am getting the same 4022 error. This
may be because of readv function.
Is there
Hi Yann,
42Kb works for me. Thanks for your support.
Regards,
Hemant

If it will flush data then at what condition it will go to apr_poll
function ??
What I understand is that if buffer is filled with 52KB data and writev is
not ready then it should go into apr_poll().
Now the problem may exist with 42KB also.
I hope I am explained my issue.
Thanks

Sorry, it did not compile, so here is v2.
With this patch, you could compile httpd with "-D
MAX_BYTES_TO_WRITEV=52000" for instance.

Yes,
Hi,
in the apache error_log with trace6, it is trying to flush because it
reached thresold_max_buffer. But at the same time, it is adding data in
buffer which increases it size to to more than 52KB and fails on NonStop.
How should I stop apache so that it should go to select function till 52KB
Hi Yann,
Thanks for your explanation. I got the issue.
Actually NonStop has maximum limit of 52KB only for writev. Therefore I was
getting 4022 after 49KB. Because after 49KB, apache is adding 8K more bytes
which leads to 56KB. Therefore, writev was failing.
To solve this, I have changed

Well, isn't the error_log attached to the previous message relevant
(be it cygwin or not)?
Btw, LogLevel trace6 would help here.

Hi Yann,
Please don't get confuse with Cygwin(Windows). I am running apache on
NonStop(Tandem). I have put breakpoint at apr_poll() but it is not going
there.
Few Events of writing :
1) apache writes 779 bytes to tomcat from apr_socket_sendv() function and
writev functions returns success.
2)

Hi Yann
I have tried to upload a file of 26.5mb on apache tomcat, which was
successfull.
I tried to proxy request to tomcat with same file. But get following error.
Attaching the error_log.
Can you please help me to understand where I am going wrong ?
Thanks

Because writev_nonblocking() is really
Hi All,
Actually it is setting sock->timeout to 0 in writev_nonblocking() in
core_filters.c.
arv = apr_socket_timeout_set(s, 0);
Why does the default timeout is changed and set to 0 ??
Thanks
