    Our server is restricting the size of file uploads somewhere. We can upload a file up to 300MB or so, but anything larger renders a page &quot;The Connection Has been reset&quot;. I have already modified the php.ini file to increase all the sizes and memory limits for uploading and it&quot;s had no effect! I am waiting on a ticket response from our server support but I&quot;m not sure how long or if they will be able to figure it out since he already told me &quot;well, keep in mind the server doesn&quot;t restrict file sizes, are you sure it&quot;s not something with your script.&quot; -- Well, I wrote a very simple upload script to test with, it only uses the move_uploaded_file() php function and I didn&quot;t code any file restrictions anywhere. We need the script to be able to upload a file up to 2GB.We need you to find out where the problem lies, whether it is the Server, PHP, or whatever! Maybe we can look through logs and find out what error is given.Please only bid if you can start right away. Thanks!

    I have a problem on which is slowing down the site load speed. We do not send mailshots from the website but there is a script running that is concatenating various mysql entries and sending something to a mailshot manager. It is consuming a huge amount of processing power that is slowing the website load to 11-14 seconds when it is normally 4 or 6. This is from Rackspace:Id User Host db Command Time State Info5144 shoes localhost shoes Query 3 NULL SELECT cat_id FROM product WHERE product_id = &quot;4297&quot; and(select 1from(select count(*),concat((select (select (select concat(0x27,0x7e,unhex(Hex(cast(mailshot_queue.mailshot_queue_email as char))),0x27,0x7e) from `shoes`.mailshot_queue limit 47966,1) ) from `information_schema`.tables limit 0,1),floor(rand(0)*2))x from `information_schema`.tables group by x)a) and &quot;1&quot;=&quot;1&quot;5143 shoes localhost shoes Query 2 NULL SELECT cat_id FROM product WHERE product_id = &quot;4297&quot; and(select 1from(select count(*),concat((select (select (select concat(0x27,0x7e,unhex(Hex(cast(mailshot_queue.mailshot_queue_email as char))),0x27,0x7e) from `shoes`.mailshot_queue limit 47965,1) ) from `information_schema`.tables limit 0,1),floor(rand(0)*2))x from `information_schema`.tables group by x)a) and &quot;1&quot;=&quot;1&quot;This happens when the CPU is peaking. As soon as these queries finish, the cpu activity dies down.Its important to note here that MySQL is running, the issue is the load it is placing on the CPU, which is your bottleneck&quot;These queries are happening constantly and we need to identify the php file that is generating them and stop it.Nigel Carr - Ltd.

    The server hosts one of our sites which handles roughly 1 million hits per month. The whole server is set up and configured already with regular backups already. I&quot;m looking for a monthly cost to manage the server. We rarely have any problems but I&quot;d love to have somebody experienced that is available to skype a few hours per month. Ideally if you have experience with optimising website speeds that would be great. I&quot;m looking to spend less than $50 per month but willing to pay per hour for extra work.Server details below:Operating System: CentOS Linux 6 - Optional Control PanelsControl Panel Software: CPanel/WHM (Linux)Processor: Quad Core 3.30Ghz HT Ivy Bridge (E3-1230v2)Memory: 32GB DDR3 ECC MemoryHard Drive: 2 x 600GB SAS 15,000 RPM + 240GB CachecadeRaid: H700 Raid Controller with BBU - Raid 1IP Allocation: 4 Usable IP Addresses (RIPE /29)Remote Management: DRAC Enterprise (Virtual KVM)Bandwidth: 1Gbps Unmetered Port - 500Mbps GuaranteedPlease let me know about your experience and how you might be able to help.

    Hi my server is on peak hour now... I&quot;m evidencing my websites down sometimes, then I have to restart httpd and mysql to back online! Ram and CPU are with low loads, so I think this is not the problem.. I think some tuning is needed on mysql, sysctl or nginx. I&quot;ll hire freelancer right now to begin with that.
