Hello! Recently, I've implemented Varnish in our websites http://www.laprensa.hn, http://www.elheraldo.hn and http://www.diez.hn. After a few navigation, I discovered that frecuently the pages get blank or their content is partially loaded. When I examined the Response Body, I found that effectively still when the pages display blank, only a few HTML content is received.
Looking for possible problems, I proceed to examine the varnishlog -i Debug -I error output, I found this error message: 400 Debug c "Write error, len = 34500/55022, errno = Success" Which appear aprox. twice by second, google give me a clue that confirm the browser behaviour, someone said that this error is showed when a client have canceled a request but he haven't received all content, and this is what has been happening, the connection is closed, before the reception of all content. Next, here are my Varnish params: param.show 200 2224 accept_fd_holdoff 50 [ms] acceptor default (epoll, poll) auto_restart on [bool] backend_http11 on [bool] between_bytes_timeout 60.000000 [s] cache_vbe_conns off [bool] cc_command "exec cc -fpic -shared -Wl,-x -o %o %s" cli_buffer 8192 [bytes] cli_timeout 5 [seconds] client_http11 off [bool] clock_skew 10 [s] connect_timeout 0.400000 [s] default_grace 10 default_ttl 180 [seconds] diag_bitmap 0x0 [bitmap] err_ttl 0 [seconds] esi_syntax 0 [bitmap] fetch_chunksize 128 [kilobytes] first_byte_timeout 60.000000 [s] group varnish (103) listen_address :80 listen_depth 1024 [connections] log_hashstring off [bool] log_local_address off [bool] lru_interval 360 [seconds] max_esi_includes 5 [includes] max_restarts 4 [restarts] obj_workspace 8192 [bytes] overflow_max 100 [%] ping_interval 3 [seconds] pipe_timeout 60 [seconds] prefer_ipv6 off [bool] purge_dups on [bool] purge_hash on [bool] rush_exponent 3 [requests per request] send_timeout 600 [seconds] sess_timeout 5 [seconds] sess_workspace 65536 [bytes] session_linger 100 [ms] session_max 100000 [sessions] shm_reclen 255 [bytes] shm_workspace 8192 [bytes] srcaddr_hash 1049 [buckets] srcaddr_ttl 0 [seconds] thread_pool_add_delay 2 [milliseconds] thread_pool_add_threshold 2 [requests] thread_pool_fail_delay 200 [milliseconds] thread_pool_max 5000 [threads] thread_pool_min 150 [threads] thread_pool_purge_delay 1000 [milliseconds] thread_pool_stack unlimited [bytes] thread_pool_timeout 120 [seconds] thread_pools 8 [pools] user varnish (100) vcl_trace off [bool] What could be the problem, maybe an incorrect configuration?
