I am running a file hosting site. I recently switched over to Litespeed on one of my large storage boxes as Nginx+PHP-FPM wasn't handling file uploads properly, but mainly due to lack of support from nginx. I was hoping that LS wouldn't have the same problem, but unfortunately it does The problem is, large file upload don't work. Problems happen when I try to upload a 300MB+ file that takes around 12 mins to upload. My PHP app receives the file once the web server okays it, but if my app can't find it/LS didn't pass the uploaded file to my app. However, a 100 MB file takes around 3-4 mins to upload and works out just fine. But, when I upload a 330MB file from a slower connection that takes around 80 mins to complete, LS just doesn't accept it. I mean, I can see LS taking in the full upload, but something unknown just happens when the file upload is complete. Although, I have set the connection timeout to the maximum possible, but it just doesn't work. I'm beginning to believe it could be a system/memory cache issues. Any ideas? My Litespeed config: Connection Timeout: 10000 Max Request URL Length (bytes) 8192 Max Request Header Size (bytes) 16380 Max Request Body Size (bytes) 1G Max Dynamic Response Header Size (bytes) 8K Max Dynamic Response Body Size (bytes) 2047M Swap is on /dev/shm (8GB RAM drive) - File uploads are temporarily stored by LS here. Here's my current setup: Ubuntu 10.04 server amd64 1 x Intel Xeon E5405 16GB RAM 300 GB SATA 10K RPM 24 x 1 TB SATA Litespeed Web Server Enterprise v4.0.15 PHP 5.2.11 LS SAPI Thanks!
