CF 6.1 - JRUN Closed Connection/Server errors occurring on a daily basis

We seem to be having issues with Jrun Closed Connection/Server errors occuring on a daily basis now. The server will stop responding to requests until the ColdFusion service is restarted.
We're using CF 6.1, the following error message is from the log files and seems to be Java/JVM related but I was hesitant to make any changes to the JVM parameters.
Any suggestions on how to resolve this daily issue of restarting CF service? Other than upgrading to more recent version of CF which we'll be doing later this year.
Thanks,
Dave

CF6, Java 1.4.2 and Windows NT - have not seen those for a long time myself.
Perhaps this is the issue from error report:
PSPermGen total 20736K, used 20580K
object space 20736K, 99% used
I guess Java non heap space Permanent Generation is full the next object trying to load into that space can’t fit, plus all the objects in there are referenced so no objects can be removed so free space can’t be made available. One would need to do some work with Java logging and know what JVM.CONFIG looks like to know if that guess is accurate.
You could try increase that parameter 10Mb or so and see what happens? In JVM.CONFIG, JVM args, -XX:MaxPermSize=NNm where NN = numbers.
Needless to say you are running a lot of end of life product and should plan to migrate to something more current.

JRun closed connection

We have two instances of JRun web connector running on two
separate IIS 6 servers (W2003). These web connectors point to two
different JRun web servers running on two separate servers (W2003).
Both IIS servers will present web pages fine for a while then
usually within a 1/2 hour I'll get "Server Error..... JRun closed
connection" While one IIS server gives the error, the other will
continue working fine. After rebooting the offending server both
will be working, then the other IIS will give the error. The error
is experienced on both IIS servers at random times but never the
error on both IIS servers at the same time. I've scoured the net in
hopes in finding an answer to this issue but no luck so far, I'm
hoping someone will know what the issue may be. Thank you.

Thanks for the input,
I found that the Hard Disk was failling 'Dirty Disk' having
replaced the HD and transfered all files I am now working again.

The underlying connection was closed: An unexpected error occurred on a receive..Exception.Message - while executing powershell command for sharepoint online site

" +The underlying connection was closed: An unexpected error occurred on a receive..Exception.Message " OR sometimes
"The remote server returned an error: (503) Server Unavailable..Exception.Message"
Getting exception above when performing various operation (site coll creating, group creation, adding users to group) for sharepoint online (Office 365) site using powershell script.
I want to create 3500 site collections using PS script. In-between getting above exception so it will skip one site collection creating and working again. for eg. after creating 11 site coll, script will through above exception and so 12th site coll will
not be create but working fine from 13 and so on...

Remote server seems working to me...any additional check?
if problem with remote server then may be loop to create site provisioning should not start again..Right?
any idea?

OLAP Error:The underlying connection was closed: An unexpected error occure

We have recently installed BPC 51 (SP2). This been working fine for months until yesterday. Now we are getting errors on OLAP Database. Following is the problem description. Any help would be appreciated.
Received error "The underlying connection was closed: An unexpected error occurred on a send." while processing dimension. This message appears during 'Create Dimension' sub step( step 2/5). After this BPC server crashes.
The same error appears while deleting appset during 'Delete OLAP Database' sub step (step 2/4). We are also not able to restore an appset since the process hangs during OLAP Database stage.

Yes we did that several time, but did not solve the problem.
Finally, we processed all the dimensions, applications, appsets within SQL server studio and the problem is resolved. I am not sure if this would surface again.
Thanks

SSRS Reporting manages goes down frequently. ERROR: The underlying connection was closed: An unexpected error occurred on a send.

We have been experiencing issues with SSRS over the past 5 weeks, the service goes down frequently. And it comes up only on reboot of the server.
We had also disabled the On Access scan in Mcafee.
The service is in use for about two years, and the below error started occuring over the last few days. Please advise on this.

Hi SThiyag,
Based on your error message, it may be related to the “SecureConnectionLevel” in the RSReportServer.config file. Please go to C:\Program Files\Microsoft SQL Server\MSRS11.MSSQLSERVER\Reporting Services\ReportServer, use Notepad to open the RSReportServer.config,
modify <Add Key="SecureConnectionLevel" Value="0"/>, change the value into "1" or "2".
(Note: Please backup the file before modify it.)
Acceptable values are:
3 Most secure—Use SSL for absolutely everything.
2 Secure—Use SSL for rendering and methods that pass credentials but don't insist on it for all SOAP calls.
1 Basic Security—Accepts http but rejects any calls that might be involved in the passing of credentials.
0 Least Secure—Don't use SSL at all

Cannot upload report to report manager 2008R2 : The underlying connection was closed: An unexpected error occurred on a receive

Hi all,
I cannot upload a report to our report manager. The message returned in report manager is: The underlying connection was closed: An unexpected error occurred on a receive
I have checked the report server log file and found the below...
Any assistance greatly appreciated.

Hi clay,
Per my understanding that you got some error when you upload reports in the report manager, right?
I have checked the log and the issue can be caused by many factors.
It can be caused by the size of the report is too big which will sent the request in its entirety and got a TCP ACK-FIN or RST from server to close the connection, without a response from server when uploading the reports. We can follow these steps
to increase the request size to resolve the issue:
Add the following registry key with the following value:
Key: HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\HTTP\Parameters
Value: DWORD "MaxRequestBytes" set it to a value of 5242880 (5MB). (This number is alterable).
Stop the SRS Windows Service.
From a cmd prompt run "net stop http" then "net start http".
Try and upload your report.
Details information please reference to this similar thread:
http://stackoverflow.com/questions/2238494/cant-deploy-or-upload-large-ssrs-2008-report-from-vs-or-ie
If the above didn't help, please also check below information:
configure the rsreportserver.config file and make the SecureConnectionLevel value set to 0 to solve the problem. By default, the file is under the path:
C:\Program Files\Microsoft SQL Server\MSRS10_50.MSSQLSERVER\Reporting Services\ReportServer
You can refer to the code below:
< Add Key="SecureConnectionLevel" Value="0"/>
The SecureConnectionLevel property allows values of 0,1,2,3, with 0 indicating that Secure Socket Layer is not required for any of the Web service methods. And a positive integer indicates Secure Socket Layer is required for all the Web service methods.
If you still have any problem, please feel free to ask.

The underlying connection was closed: An unexpected error occurred on a receive

Hi,
We have a requirement where we need to create a custom workflow code activity which will download the current uploaded document to a shared network drive. We have created a code activity using client object model to achieve this. But intermittently
below exception is being occured at ctx.ExecuteQuery();
Can anyone help me in resolving the issue?
Exception :

LogMessage("In Using");
ctx.FormDigestHandlingEnabled = true;
Web web = ctx.Web;

ListItem item = GetAllListItems(web.Url, strListName, strItemId);
LogMessage("in loop1"+item.DisplayName);
foreach (Microsoft.SharePoint.Client.File file in GetListItemAttachments(web.Url, item, strListName))
LogMessage("in loop2");
SaveAttachmentToDisk(file, strFilePath, web.Url);
string fileExt = System.IO.Path.GetExtension(file.Name);
string newName = file.Name.Substring(0, file.Name.IndexOf('.'));
newName = newName + "-" + curDate;

Hi,
According to the error message, it usually occurs when server or network device unexpectedly closes an existing Transmission Control Protocol connection.
This problem may occur when time-out value on the server or network is set too low.
To resolve this issue, I suggest you do as the followings:
1. Configure the Web site that hosts the Web services not to use keep-alive connections.
2. Override the HttpWebRequest method in the Reference.cs file that is generated by Microsoft Visual Studio .NET for the Web client proxy.
protected override WebRequest GetWebRequest(Uri uri)
HttpWebRequest webRequest = (HttpWebRequest) base.GetWebRequest(uri);
webRequest.KeepAlive = false;
return webRequest;

The underlying connection was closed: An unexpected error occurred on a send.

Fala ae galera.
tive problemas ao publicar meu primeiro report, exibe o seguinte erro: The underlying connection was closed: An unexpected error occurred on a send.
Configurações IIS

Hello,
Based on the error message, the issue may be related to the “SecureConnectionLevel” in the RSReportServer.config file. When we use HTTP protocol, the value of the “SecureConnectionLevel” attribute should be 0. Usually, we change the value to “1” or “2” only
when we configure the Report Server for Secure Sockets Layer (SSL) connections.
Reference:
http://msdn.microsoft.com/en-us/library/ms157273(v=sql.105).aspx
Please refer to the following steps try to resolve the issue:
1. Use Notepad to open the RSReportServer.config. By default, in SSRS 2012, it is located in: C:\Program Files\Microsoft SQL Server\MSRS11.MSSQLSERVER\Reporting Services\ReportServer
(Note: Please backup the file before modify it.)
2. Search for “SecureConnectionLevel” and make sure its value is set to 0. It looks like this:
<Add Key="SecureConnectionLevel" Value="0"/>
There is a blog about “The underlying connection was closed…" error message, you can refer to it.

Register-SPWorkflowService : The underlying connection was closed: An unexpected error occurred on a receive

My Fellow SharePoint 2013 Engineers,

Since I didn't get any response back, I turned on all the loggin on our SharePoint environment and ran the powershell command again. I got the same error. I searched for the Client ActivityID on the log file and found the below. Can anyone shed some light
on it?

[Exchange-Online] [EWSMA] [C#] [Windows]: EWS - CreateAttachment problem - The underlying connection was closed: An unexpected error occurred on a send

Hello,
I have a problem with
ExchangeServiceBinding.CreateAttachment(...) method (EWS with Office 365)
When I try to add a small attachment (e.g. 5 MB), then the method works fine.
When I try to add a big attachment (e.g.
12 MB), then the following exception is thrown:

// Upload attachment

// Check response errors

Could you advise a solution, please?

Hello,
The maximum size is rather not the problem in this case. As mentioned in my question above, I have a problem uploading messages with 12MB attachments to Office 365 via EWS. According
to the documentation you provided a link to, the message size limit in all plans of Office 365 is 25MB.
When we try the same request using slow network connection (1Mbit/s) there IS problem - we are NOT able to upload 12 MB attachments.
When we try the same request using faster network connection (10Mbit/s) there is NO problem - we are able to upload 12 MB attachments.
It seems like a kind of timeout - probably from Office365.
Is there a possibility to upload attachment in chunks?
Robert

URGENT - The underlying connection was closed: An unexpected error occurred on a send

Hello,
We have a web app that works with Ping Federate SSO. The code that was working fine suddenly stopped working with this error message.
Code: httpResponse = (HttpWebResponse)httpRequest.GetResponse()
Error: The underlying connection was closed: An unexpected error occurred on a send
We have tried everything to try to make it work. Made sure TLS is enabled, review the logs from both sides. Nothing seemed to work. I read on the net that there appears to be some known bug with the .net framework.
This is our prodcution code and our customers are currently impacted by this issue and we need to get the SSO working again.
I'd appreciate if you can email me how we can go about resolving this issue. BTW, I also made sure have the correct certificate through IIS bind.
regards,
Ilanko

I can´t set the control panel iCloud. PC writes this: you can not connect because the server error occurred. What´s matters?

I can´t set the control panel iCloud. PC writes this: you can not connect because the server error occurred. What´s matters?

Whenever I log into icloud.com
Using what version of which browser?
iCloud.com requires Safari 6 or later, Firefox 22 or later, or Google Chrome 28 or later. Have you tried all of those?
If you have, have you tried clearing your browser cache and cookies?
For the first tine since 1989 I'm thinking about buying a PC.
You'd have exactly the same problems on an 8 year old PC too. It's a bit unreasonable to expect such an old Mac to continue to be compatible as software is constantly updated.
Saying that, I'm still able to access iCloud.com successfully in Safari v5.0.6 on a PowerPC Mac running Mac OS X 10.5.8, so the problem you're having is likely to be a browser issue, not something inherently wrong with the computer.
Since all this crap started, Mail won't download my Mac.com or me.com email.
The iCloud.com website is totally unconnected to Mail's ability to download email via IMAP. Have you checked the mail server settings are correctly setup and up-to-date?

A server error occurred on the current command. the results if any should be discarded in SQL 2008 R2

Hi,
I am using SQL server 2008 R2 and also MultipleActiveResultSet = true and Pooling = true (default value) in connection string.
While executing query 'IF ORIGINAL_LOGIN() = SUSER_SNAME() EXECUTE AS USER = 'MyUser'', I received error stating 'A server error occurred on the current command. the results if any should be discarded'. At the same time I could check that SqlConnection
state is also closed.
I have also fired 'REVERT' query If I find such exception and again try to execute same query again. but no luck. I received the same exception while executing query (Execute As) again.
What can be the solution to avoid such exception and make my code working?
Thanks,
Ashish

Login failed for user 'sa'. The user is not associated with a trusted SQL Server connection.
Above issue occurs genrally when authentication mode is set to Windows Authentication insted Mixed Mode.
You can change the authentication mode of the SQL server from “Windows Authentication Mode (Windows Authentication)” to “Mixed Mode (Windows Authentication and SQL Server Authentication)”.
Run following script in SQL Analyzer to change the authentication
LOGIN sa ENABLE
GO
ALTER LOGIN sa WITH PASSWORD = '<password>'
GO

But as per the first post it seems issue is different have you observerd Error log?
Check out at C:\Program Files\Microsoft SQL Server\MSSQL.n\MSSQL\LOG\ERRORLOG
Location might differ as per the Server configration
