Hi there, we are running version 3.3.14 with LSAPI php (php version: 4.4.9, LSAPI version: 4.1) we are hostin approximately 280 php domains and couple of rails applications (5 I think of which 3 are being frequented more) on a 2-CPU box with 4GB of RAM. Recently we started to run into connection timeouts to the lsapi php socket: Code: 2009-12-20 13:35:34.066 [INFO] [126.96.36.199:48960-0#APVH_***:80] connection to [uds://tmp/lshttpd/global-php.sock] on request #24, error: Connection timed out! and connection resets Code: 2010-01-28 09:26:42.014 [INFO] [188.8.131.52:11879-0#APVH_***:80] connection to [uds://tmp/lshttpd/global-php.sock] on request #13, error: Connection reset by peer! Connection timeouts are occurring only during high traffic, connection resets are present all the time. By high traffic I mean 100 concurrent connections. Could you please shed some light into how we could improve things so we wouldn't get into connection timeouts so easily? I am including some configuration: General Code: Priority:15 Memory I/O Buffer:1G Tuning/Connection Code: Max Connections: 200 Max SSL Connections: 100 Connection Timeout (secs): 300 Max Keep-Alive Requests: 20 Smart Keep-Alive: Yes Keep-Alive Timeout (secs): 5 Send Buffer Size (bytes): 0 Receive Buffer Size (bytes): 0 Security/External Application Resource Code: CPU Soft Limit (sec):300 CPU Hard Limit (sec):600 Memory Soft Limit (bytes):500M Memory Hard Limit (bytes):600M Process Soft Limit:50 Process Hard Limit:50 LSAPI PHP Code: Name : global-php Address: uds://tmp/lshttpd/global-php.sock Notes : Not Set Max Connections: 200 Environment: LSAPI_CHILDREN=200, LSAPI_MAX_REQS=100, LSAPI_MAX_IDLE=20, LSAPI_MAX_IDLE_CHILDREN=1 Initial Request Timeout (secs): 300 Retry Timeout (secs): 0 Persistent Connection: Yes Connection Keepalive Timeout: 5 Response Buffering: No Auto Start: Yes Command: $SERVER_ROOT/fcgi-bin/lsphp Back Log: 100 Instances: 1 Run On Start Up: Yes Max Idle Time: 20 Priority: Not Set Memory Soft Limit (bytes): 300M Memory Hard Limit (bytes): 500M Process Soft Limit: 80 Process Hard Limit: 100 Thank you!
