Opitsk: network error occurred while two-task server trying tosend break

Problem Description: Environment Details
Application Server : Version 10.1.2.3.0 on Windows Server 2003 R2
Database Server: I have installed Oracle DB (11.2.0.1.0) on the same sever having Oracle 11g Release 1 (11.0.7.0) and Oracle 10g Release 2 (10.2.4.0).
I am using Oracle11gR1 listener for all three databases.
I have created database for Oracle11gR2 with no issues at all.
Issue:
Now when I am running my application using Oracle11g R2, my application runs fine for a specific interval after which I get ORA-03113: end-of-file communication channel. All the Sessions linked to these are all dead.
From the logs I discovered this (which is TNS Packet write failure)
opitsk: network error occurred while two-task server trying tosend break; error code = 12571

Any clue based on the Trace file???????????

Error occurring "opitsk: network error occurred

Hello All,
Platform : Windows-2008Server 32 bit,Oracle10gStandard,OracleFS 3.4
I have two cluster nodes(NPRDB1, NPRDB2) with Microsoft clustering and Oracle Fail Safe. The Oracle database is hosted at a common node PRDB. All my services (including my application’s ) were up and running on primary node. My application’s service connects to the database in NPRDB through a DSN.
Now I have another Server (NRP2) (which is not a node in the cluster) , which also has my application’s service running and it is also connected to the same database on PRDB through a DSN.
A peculiar thing happened when I restarted the NRP2 machine when services were running fine on the cluster nodes.
We started getting database disconnection errors on the Primary cluster node.
Oracle gave the following log : *** 2010-02-21 23:51:02.215 *** SERVICE NAME:(SYS$USERS) 2010-02-21 23:51:02.200 *** SESSION ID:(45.60) 2010-02-21 23:51:02.200 opitsk: network error occurred while two-task server trying to send break; error code = 12571
Windows Event Log on Primary Node
Oracle MSCS Service : Oracle Fail Safe successfully took resource PRDB offline
Error on Standby Cluster Node:
Cluster resource 'PRDB' in clustered service or application 'NPRDB' failed.
Any pointers or reason for the above problem?

A network error occurred while trying to communicate with the server.

Hello All,
I am getting some new error messages when opening the server app on my Mac Mini server running OS X 10.8.2 and Server 2.2.1. First I get a message that says "A network error occurred while trying to communicate with the server." and then after trying to open some of the service panes, I get additional errors that say "Multiple errors occurred on the server while processing commands." The services don't load and I just see "Error Reading Settings" in the server app.
I started to get these errors when I added a new website to the server. All the services are working fine but I cannot access them in the server app.
In console I'm seeing these errors when I try to access various services:
2/24/13 8:02:12.692 PM Server[956]: Error: The server '10.0.1.150' reported an error while processing a command of type: 'readSettings' in plug-in: 'servermgr_dns'.

I have already restarted the server and used terminal to stop and start postgres. Any more thoughts on how to repair this?

Just as I had suspected, the whole GUI crashed because of certificate problems. After two and a half hours with enterprise support, it turns out the com.apple.servermgrd certificate in the server keychain had become corrupt.
We determined this by typing https://127.0.0.1:311 into Safari and we could see all the server modules and interact with them through the web interface. All the services were working properly as well so we knew that it was just the Server.app GUI that simply couldn't read settings that was causing the problem.
So, first we closed the server app. Went into /var/servermgrd and deleted all the files from this folder. Then, in Keychain, deleted the com.apple.servermgrd certificate. Did a search for com.apple.servermgrd in Keychain and deleted everything else that came up for it.
Then restarted the server. Now the server app was able to properly connect to the services in the background and read them properly. This was the jist of the troubleshooting that solved the problem. It also seems like DNS is causing problems because that is the only service that will not read right but is functioning properly in the background.
I will post an update once Apple figures out what is wrong with DNS. Hope this helps anybody else having these problems.

A network error occurred while accessing this document on the internet

Dear all,
I am now facing a very unusual problem that, when I try to open a pdf file from internet, it says: "A network error occurred while accessing this document on the Internet. Would you like to close the document or reload it?". Here's my situation:
Browser: IE8 (or Chrome 35.0.1916.153)
Adobe Reader: 11.0.0
OS: Win7
1.Directly open from IE. Says: "A network error occurred while accessing this document on the Internet. Would you like to close the document or reload it?"
2.Try to download(Save AS). In IE, says: "The connection was reset The connection to the server was reset while the page was loading"; In Chrome, nothing happened, but still can't download.
3.Try to disable the "PDF Reader Addon" in IE8. First the browser needs to download the PDF file, but failed, see point 2.
1.I can open the same PDF file from another network, that is, out of my company.
2.I can open another PDF file in the network of my company, but the pdf is created by another scanner
3.All PDFs from both scanner can be opened locally.
So, here's the possible problem, the network settings, and(or) the PDF. Does anyone ever meet this situation, please help?
Thank very much.
Li

Rave,
IE: 8 & 9
Adobe Acrobat Pro/Acrobat Reader 10.x & 11.x
Chrome: work fine
So the answer is to manually enable and disable websites based on whether the pdfs open within the browser. That doesn't seem like a great long-term solution to have have our users to manually enable / disable browser integration. We have web applications that work better with browser integration turned on. Is this something that Adobe will fix or is it an IIS/IE issue.
It appears the Adobe removed the #1 config option that you lised in the new 11.x versions of both products. The manage Add-ons does not disable the browser integration on the new Adobe versions.

I get the billing part up, it has even uploaded my jpegs but at the final process, I get the same message.
I have ordered two books a few months ago without any problems.
Now I keep getting the same message either half way into
the order or at the final hurdle after the images have been uploaded.
Any ideas?
My shared Network has been fine and that does'nt seem an issue.
Help.

Image Ultra Builder 4.0: "An error occurred while connecting to server: Check the server"

Ladies & gentlemen
I am using evaluation version of ImageUltra Builder 4.0 for Windows
XP. Both server and console have been installed on the same machine.
When I try to add a new repository, then after pressing the final
"Finish" button I get the message "An error occurred while
connecting to server: Check the server".
This message appears when the service IUServer runs.
I have not found any mention of this error neither in the Internet nor
in the documentation. Can any one suggest what could have been done wrong?
Thanks, Ilya Druker

I've had the same problem when trying to generate a database on an external storage unit. When I create a new repository there are two option:
1) Location: - This is the location where you want to store the files itself. This server does not have to have a database running on it
2) Server: - This is the name of the server that actually runs the DB2 database that keeps track of the repositories. This server does not have to be the same as the location where you store the files. This could also be the IP address of the server, not necessarily the name.
The documentation for this is somewhat confusing, but the above stuff works atleast. I have tried in never versions than 4.0 as well.

Error : "A network error occurred while accessing this document on the internet"

When i try to open un large pdf file (120 Mo with many picture inside), an error appears : "A network error occurred while accessing this document on the internet. Would you like to close the document or reload it" . But if i try to "save as" the pdf on my disk, it's work.
I also try to change the option to open the pdf directly in the Adobe reader and it's work. But if i retry to open the pdf in the browser, the error reappears.
The file is located on a secure server (https) with a user and password.
Does anyone know how to fix it?
Thanks!

I try with Internet Explorer 6 and 8.

Also, do smaller sized PDFs open successfully at your end?
Yes it does
I also tested with French and English versions. Acrobat Professional X seems to react the same way but Adobe Reader 9 works!
