Hi all,
The HTTP proxy uses the HTTP_IN filter to read from the network. The
proxy code seems to be working fine, however about 10% to 20% of
requests fail with this error:
[error] (9)Bad file descriptor: apr_bucket_read
The error occurs part of the way through a read from the remote server,
and sometimes results in a partially loaded graphic or page, or
sometimes no graphic or page at all.
The error is generated by this piece of code in ap_http_filter():
e = APR_BRIGADE_FIRST(ctx->b);
if ((rv = apr_bucket_read(e, &ignore, &len, mode)) != APR_SUCCESS) {
/* probably APR_IS_EAGAIN(rv); socket state isn't correct;
* remove log once we get this squared away */
ap_log_error(APLOG_MARK, APLOG_ERR, rv, f->c->base_server,
"apr_bucket_read");
return rv;
}
The HTTP_IN filter is normally used for reading client requests off of
the network. In theory, if this error exists in HTTP_IN it means that
about 10% to 20% of client POST requests are likely to fail.
Does this error ring any bells with anyone?
Regards,
Graham
