Hi, all. James, thanks for your response. Yes, the issue is bothersome, but it does *not* occur with great frequency and has been a known issue for a while. GK has a workaround for the issue in place. Naganand and I wanted to throw it out to the community to see what options were available. As GK has been up and running on all branches, you'll see more participation on the listserv.
Don't worry--high priority issues for active deployments are quite naturally handled with due concern, and in fact I am in Bangalore for several months to generally pester Naganand, document how Mifos is being used in the field, and identify pain points to be fixed ASAP, as well as supporting other deployments in India. (If you are curious about what the issues are, check the issue tracker with keyword GrameenKoota, the Deployment Issues page, or the Ongoing Issues page). http://mifos.org/developers/how-mifos-is-used gives a short picture of how it's really being used (though I suspect you know some of it already ;) ) Aliya has also looked into the issue already and likely a defect will be filed by Grameen Koota. Thanks again for noticing and please feel free to work on the patch ;).

It sounded to me like a pretty big deal, requiring some sort of immediate response at a technical level. Sorry to jump on toes, but was there a response off listserv? The likely problem here is that the database connections are being opened and not closed properly (each query is left open as a separate connection ) - so someone with good hibernate chops might need to be drafted into this (Sam Lee - I see you are active now and I recall you had this skill?). Maybe this link would be helpful? http://www.informit.com/articles/article.aspx?p=353736&seqNum=4 At a minimum, it looks as if the stress testing regime and unit tests around this are weak. (Hiya Naganand - hope you are doing well. ) - James ---------------------------------------------------------------------- Message: 1 Date: Mon, 12 Nov 2007 05:42:09 -0500 From: "Amy Bensinger (Contractor)" <[EMAIL PROTECTED]> Subject: [Mifos-developer] FW: Information on database performance and optimizations?

From: Naganand [mailto:[EMAIL PROTECTED] Sent: 12 November,2007 04:00 PM To: '[EMAIL PROTECTED]' Subject: Hi all, Greetings from Grameen Koota! We have an issue on our live server. Can anybody help us! We have 44 branches running live on the server and most of them do data entry using low speed internet connections. The connection is sometime strong and sometime week and breaking. It so happens that sometimes mysql on our database server overshoots the number of users which is currently defined as 150 [though the number of branches are only 44 + another 10 users max] and the server hangs and stops responding. If I increase the users limit then the server starts responding slowly. Also sometimes the branches load reports and there is a connection breakage inbetween. Then the users reconnect and reload the reports. But in the server the old queries does not end and mysql hangs. We need to restart mysql or kill the queries 1 by 1 and then the server works faster. Can anybody help us know why does the no. of users go out of limit? And why do the queries hang instead of ending when the user is disconnected from the net?
