    I have a membership site built in Wordpress, with Strongbox security. I use CCbill as payment provider.I had it changed from Dreamhosters hosting to Godaddy hosting.Since it was changed I am having issues with the site being really really slow and crashing.I get error messages like this, and then the site crashes:***** Nagios *****Notification Type: PROBLEMService: HTTPHost: tanyatate.comAddress: XXXXState: CRITICALAdditional Info:CRITICAL - Socket timeout after 10 secondsIt"s running out of memory or having a memory leak issue. I understand there has to be a setting or resource or something that"s unnecessarily consuming too much memory or processes getting hung up somewhere. My old server at Dreamhost was only a VPS with 1GB of RAM. The new server is a dedicated box with double the RAM previously had. Also a new sub account has been created in CCbill for subscriptions. Repoint the current memberships to go to the new sub account, ensuring smooth changeover and Strongbox works with the new sub account.

    We have a dedicated Windows 2008 webserver which we use to host a couple of high traffic websites. Lately the sites hosted have been receiving a large number of FastCGI errors, and often keep going down.We have modified a number of FastCGI and Application Pool settings in order to try and stop this, but the errors seem to be happening more now. One of the sites hosted receives 20,000 visitors per day, and we also have a successful iPhone and Android app which communicates with our server too.The server has typically been very stable in the past, and the sites have performed well with a lot more concurrent visitors also, but the errors are ocurring so frequently at present that we"ve had to set the application pools to recycle every 20 minutes, which by experience is not good.We would like somone to login to our server and take a look at the settings, and advise why the FastCGI errors keep ocurring, and fix them.
