Hi All, I am getting lot of CLOSE_WAIT ,SYNC_RCV and TIME_WAIT state when I do a netstat and result it is Apache pause. What would be the ideal approach to solve the issue.I am planning for explicit call of ap_lingering_close after reading the client request.
Also I see a #ifdef CORE_PRIVATE under httpd_connection.h where ap_lingering_close is defined and the macro #define CORE_PRIVATE is defined in mod_proxy.h.But I don't use mod_proxy so is it going to impact anything? For TIME_WAIT plan to reduce tcp_max_tw_buckets value.Is it going to be impacted? For SYNC_RCV Increasing net.ipv4.tcp_max_syn_backlog, decreasing tcp_synack_retries and enabling tcp_syncookies. If you have any suggestion then please let me know. Thanks in advance. -A
