xml - Restarts c# windows service on a url call -


i have c# application runs windows service. application uses open source tiny http server url communications. there flext application developed update , select data sqlite database via c# application using get/post methods.

i have url called https:/domainname:portnumber/folder/tree/200 reads data database of c# service , returns huge amount of data in xml form client.

some times when url gets called totral c# windows service getting restarted. , needs refresh flext application start again. server firewall windows service installed turned off , machine reachable.

when checked log found after url call, server restarts. also, when checked traffic in fiddler got error below:

http/1.1 502 fiddler - connection failed content-type: text/html; charset=utf-8 connection: close timestamp: 10:18:52.685  [fiddler] socket connection (domainname) failed. <br />errorcode: 10061.

the code used calling folder/tree below

public string tree() {     try     {         string langstr = "";         if (request.querystring["lang"] != null && !string.isnullorempty(request.querystring["lang"].value))         {             langstr = request.querystring["lang"].value.tostring();         }         else         {             thingzdatabase db = sessiondatabase;             langstr = db.defaultlanguage;             db = null;         }          foldertree = new foldertree(convert.toint32(id), true, sessiondatabase, langstr);         xmldocument doc = foldertree.xml;          response.contenttype = contenttype.xml;         langstr = null;         foldertree.db2 = null;         foldertree = null;         //gc.collect();         return doc.innerxml;                         }     catch (exception e)     {         touchserver.log(logger.messagetype.error, 1, e.tostring());         return "get folder tree failed, reason:" + e.message;     } }

to execute query sqlite database code below used

public sqlitedatareader executesql(string sqlexpr) {     if (conn.state != connectionstate.open         open(datafile);      using (sqlitecommand cmd = conn.createcommand())     {         cmd.commandtext = sqlexpr + ";pragma read_uncommitted = 1;";         cmd.commandtype = commandtype.text;         return cmd.executereader();     }           }

whats size of return string? write file verify length of return string.

there may problems web service if length exceeds limit.

the following link discusses similar problem. http://social.msdn.microsoft.com/forums/en-us/wcf/thread/58e420e9-43a3-4119-b541-d18158038e36/

the service may crash if have not handled exception.
