Re: Cancel ongoing ngx_http_request_t

Ok, so I managed this to work, needed to add ngx_http_send_header and ngx_http_finalize_request:

static void simple_timeout_handler(ngx_event_t* timeout_event)
ngx_int_t result;
ngx_http_request_t* request;

ngx_log_debug0(NGX_LOG_DEBUG_HTTP, timeout_event->log, 0,

request = (ngx_http_request_t*)timeout_event->data;

result = ngx_http_send_header(request);
ngx_http_finalize_request(request, result);

Everything work fine, but during the load test, after some time, a SEGFAULT occurs:

Thread #1 [nginx] 3352 [core: 7] (Suspended : Signal : SIGSEGV:Segmentation fault)
ngx_destroy_pool() at ngx_palloc.c:51 0x405187
ngx_http_free_request() at ngx_http_request.c:3,499 0x42f04b

ngx_single_process_cycle() at ngx_process_cycle.c:308 0x423c8b
main() at nginx.c:416 0x403bc6

It seems, that pool argument passed to ngx_destroy_pool is not initialized, any ideas why this could happen?
