Thank you for bringing this matter to our attention. We have been hard at work looking into the Apache failure on this server. In the late evening of yesterday, Sunday the 25th, the Apache web service had failed on this server. While the server was still online and operational, the Apache service (which handles all website traffic) was unavailable. The specific error pertaining to this problem involved the Apache service hitting the maximum amount of file handles permitted to be opened by a given system process. Despite various attempts to increase this limit (both the server's soft and hard cap), the problem remained. The issue at hand was simply that, while our server is *more* than capable to handle such a file handle load, the server's kernel was limiting the file handles to a default value.
After much investigation and Apache recompiling we were able to determine the original cause for the sheer amount of file handles that Apache was opening. As mentioned, our server is more than powerful enough to handle the level of file handles that Apache was attempting. The server was operating within optimal server performance ranges. The limitation of file handles per-process placed by the system kernel is something that would take significantly more downtime to modify. We are very pleased to have located the original cause as to eliminate the need for such further downtime.
At this time the server is running without any problems and within optimal levels. You should not expect any further problems with this server. Having located the origin of the issue, we can assure you such a problem will not reoccur. If you experience any anomalies with your site, please reply to this ticket so that we my immediately investigate and resolve the matter.
As mentioned, the only service affected was the Apache web server daemon. This means that the mail server, ftp server, and all other services on this server were in full operation throughout this issue. Any mail sent during that time will have delivered properly and was unaffected by the problem experienced with Apache.
I thank you for your patience during this outage and please accept our apologies for the inconvenience. An outage as lengthy as was experienced is far from acceptable. We are confident that as a result of our investigations we can assure this issue will not reoccur in the future.
If there is anything that I can do to ensure that this matter is fully resolved to your utmost satisfaction, please do not hesitate to reply to this ticket. I will be happy to help.
