Subject: ISP Use
Date: Mon, 09 Dec 2002 13:51:47 -0800
From: "SBWH.com Support" <support@sbwh.com>
Hello from Santa Barbara.
We suggest Snitz to many clients for an easy forum, but we are seeing a lot of problems with the
database becoming unusable due to two users accessing it at once, or heavy load on the server.
Restarting IIS fixes this.
This weekend, Microsoft did a memory dump for us to find problems, and they said the snitz forum
is trying to access critical memory space, and having problems
Do you know about these issues, or have any ideas around them? We be happy to purchase support or
upgrades?

Curious, and call me stupid If you want to :) but it just doesnt quite 'gel' for me, Snitz doesnt actually access any memory, its Microsofts own ASP, IIS, ADO, Windows Server technology doing all the memory accessing.

I completely agree with Gremlin, Snitz does not access any memory it is purely an asp application.
This forum sits on a standard win2k server, it access a SQL server on a seperate machine which also has many other active databases, some more so than Snitz, I can categorically state that Snitz does NOT have any advers affect on the server and uses no more resources than any other NON Snitz site which also access the SQL database.
Having said that, I would also say that it is not suited to a server hosting 100's of sites, not that have any kind of traffic anyway but that is not really a Snitz issue, it is the way SQL and IIS deal with memory.
I have seen over 5000 concurrent users access a Snitz/SQL setup with no affect on any of the other sites sharing the servers. |

| I agree with the comments both by HuwR and Gremlin, but I thought that the problem, although uncorrectly attributed to Snitz accessing restricted memory in that email, might be related to heavy server load posed by previous Snitz versions. Thus my question... |

Oddly enough I've been troubleshooting and huge memory leak problem on my server which requires me to restart every evening. I have 1.5 gigs of DDR PC2700 and during the course of the day it drops to 300 megs at its worst before restarting.
I am happy to report that I have eliminated Snitz and the Mods I have installed.
On a sad note, I still have not figured out why this is happening. I am going to do some major testing this weekend with a rebuild of the drive and try to eliminate any hardware problems that I may be having. |

ruirib,
Even the previous version did not consume excessive amounts of ram, I should know I host quite a few.
dayve,
does task manager not show you what is using the ram ? |

It would be interesting to see Microsoft's proof to this claim:
"This weekend, Microsoft did a memory dump for us to find problems, and they said the snitz forum is trying to access critical memory space, and having problems" |

That is a possibility, but normally just stalls the asp engine, the mail components don't generally increase their ram usage the more mail they send, so it is not likely to be causing memory problems.

My question to microsoft would be which one of your BUGS is allowing an ASP application to access critical memory areas  |

This may or may not be true but I have letters from my host indicating that in their experience past versions consumed far more RAM than they should have. I wish I saved some links for you but I have seen similar statements elsewhere. It could be all the MODS people use and I'm sure that MODs are a major source of RAM issues but my host hinted that when they have a server resource problem and a user has a Snitz forum they check that account out first.

nobody is denying that earlier versions could consume more memory than normal, but thatis not what is being said here

plus as I said before, I have hosted this forum for quite some time, and am fully aware of the different memory requirements of the previous versions, but as I also said previously, it has NEVER caused a problem on any of my servers , if you are going to stuff say 200 sites on a server though, you are going to run in to problems even with low useage sites, just work it out, lets say it has 2Gb of ram (a rarity in web servers) remove about 200Mb for the system and divide by 200 it leaves about 9Mb of ram for each website, even for a website doing absolutely nothing at all that is very little. |

sure, I use task manager as well as another memory manager utility. The problem is that although I see how the ram is being distributed, I am not reallocating ram back when certain things are close/ended etc. my SQL Server is the biggest consumption of RAM, but I still have not figured out where I am losing the memory. I will lose about 5 megs of ram every 10-20 minutes that is unrecoverable, even with my memory manager. |

dayve,
SQL server will take as much memory as it is set to have, it does not give it up readily even if it isn't useing it, so if it is consuming too much, set it a lower limit, although you may get performance issues if you do, by default SQL asigns 1024K for each querry, you could try reducing this to reduce your sql memory useage.
IIS is pretty much the same, but there is no way to limit how much it uses, other than setting low session timeouts etc.
what sort of amounts are we talking, and how much ram does your machine have ?
The SQL server here uses 1.5Gb of ram on its own, and would use more if i gave it to it. |
