BizTalk 2013 SFTP Adapter : Host Instance configured for SFTP Receive cause high CPU usage

Hi,
Our BizTalk 2013 Server test env have 16 GB RAM. We have one SFTP Receive Location which is using a dedicated Host instance for SFTP receive.
As soon as we start this SFTP Host Instance it starts consuming 50-60% CPU. (Even when it is not handling any file receive)
As suggested in below thread, to fix this issue, we changed the SFTP RL default configuration. i.e. Changed polling interval from default 0 sec to
10 minutes and also changed the RL Schedule window to business hours only.
https://connectedpawns.wordpress.com/2014/04/13/biztalk-2013-sftp-adapter-biztalk-host-receiving-throttled-because-processmemory-exceeded-the-configured-throttling-limit/#comment-2602
Even after changing the RL configuration , the Host Instance continuously consumes ~60% CPU.
Any suggestions to troubleshoot more on this issue ?
Thanks in advance !!

This is one of the issue which has already been raised to Microsoft and hopefully a public build will be available soon in next cumulative update pack .
There are variety of reason for this starting for password mismatch or password not given , SFTP adapter unable to connect and so on .
There is good post here in below link for this issue

Another greate artcicle is by Nino which states these issues .SFTP adapter is protocol sensitive and some configuration by server side, can cause a lot of crazy situations

BizTalk 2013 SFTP Adapter Dynamic SFTP send port exception: Open remote file for write error

I am using BizTalk 2013 SFTP adapter. I defined a Dynamic One-Way
send port on BizTalk server administration.
Below is the error I'm getting on BizTalk while trying to write files to a designated folder on a client's SFTP server.

Hi Yaeli1,
From the error message above, please check the permission for file writing , it seems that this issue is related to access permission.

IDoc receiver AEE: Error "Configuration for Sender/Receiver Partner Number/Port is incorrect"

Hi all,
We are on PI 7.4 AEX SP 7. We are trying to get the following scenario working: Inhouse warehouse management system (JMS) --> PI --> ECC (IDoc)
Sender is configured as 3rd party technical system system with business system maintained in SLD
business system has logical system assigned in SLD
adapter specific identifiers show logical system in ID / NWDS
logical system is defined in receiver (ECC system)
partner profile is created in ecc for this very logical system (inbound parameters)
No mapping of EDI_DC40 node in ESB (complete node disabled)
no header mapping in ID / NWDS
receiver IDoc AEE adapter is configured to not enforce control record (Control Record in IDoc XML = Not Mandatory)
no Identifiers specified in receiver IDoc AEE adapter
My guts feeling is that this should work, however, it doesnt't. Failing with "The Configuration for Sender/Receiver Partner Number/Port is incorrect. Enter proper values in Sender/Receiver Component"
Any thoughts are highly welcome.
Cheers
Jens

Hi,
The error mentioned by you is not related to the port..but its related to the Application ...
IDoc 51 means idoc has been received in R/3 client and when it tries to process it ended in error..
Check with the functional consultant for the error you have received..

High CPU usage because of Biztalk Server

How do you prevent Biztalk Server from causing the CPU to go high?
Christiane

Hi Christiane,
To prevent
BizTalk Server from causing high CPU, identify the root cause and solve it.
Analyze the performance counters, as
Tomasso suggested start with
PAL tool and analyze its report.
MessageBox viewer should also give you indicators with critical errors.
More often it’s due to tracking. Check the level of tracking enabled. Make
sure the SQL Agent jobs are all working as expected to clean up the BizTalk tables.

High CPU Usage in Word 2013

Hi everyone,
I'm having an issue with Word 2013 and I'm hoping someone can help. Seen as I got fleeced for my TechNet subscription this year (the price given on the invoice doubled when I called up to pay!) I’d very much like to see a speedy fix from the Microsofties
please! :D
Recently, I've found that Word will consistently exhibit high CPU utilisation, ~50% on a dual core second generation Core i5.
This continues, even when I’m not providing any input to or interacting with the Word window and even when the Word window is covered by other windows. Minimising Word causes its CPU usage to drop back down to zero.
The strange thing is that, so far, I’ve only observed this with a single document. I started writing this document at the start of this week and it’s been authored exclusively on Word 2013. In fact I’m the only one who’s editing it and I’ve only used a single
computer (and this one single install of Word 2013) to do so…
There’s nothing particularly unusual about this document, and a different but similar document which uses the same themes and features (in fact the theme for the second document was created from the first one) doesn’t appear to cause the same issues. Both
these documents are stored on SkyDrive, and are being edited directly from there.
Initially I tried the much recommended tweaks of disabling hardware graphics acceleration and sub-pixel positioning, however neither of these has had any effect.
I investigated a bit further using Sysinternals Process Monitor, and found that while Word is using a lot of CPU it’s actually looping very, very quickly polling for the existence of the registry key “HKCU\Software\Microsoft\Avalon.Graphics”.
This key doesn’t exist on my system, and a quick test I conducted where I created it just lead to Word looping polling for more non-existent registry keys.
My system is a HP Folio 13 running Windows 8 Pro x64 with Office 2013 (RTM, not Beta) 32 bit. Both Windows and Office are fully patched, as is everything else on the system.
Thanks in advance for any help anyone can offer.
Chris

Hello again,
After working on my problematic document some more, I believe I’ve found the cause of the issue.
@Microsofties – I think this one is either a bug or a dodgy OOTB template…
I noticed that the high CPU usage only seemed to occur when the document’s footer was displayed. Experimenting with some careful scrolling and zooming to hide footer (without actually using the “hide white-space” option) seemed to confirm this so I investigated
the footer a bit more.
My document was using the standard Word “Facet (Odd Page)” footer template with a couple of fields added to suit my needs, namely “Publish Date” and a page number.
The template seems to be structured such that the content of the footer is inside two nested text boxes (one inside the other). I also noticed previously that this footer template also appears to “jump” up each page and back down again as I scrolled.
So I deleted the footer and its text boxes, and recreated the same content, in the same position (using the standard paragraph alignment tools) by hand without the nested text boxes. This has, so far, fixed the issue!
I also noticed that the CPU usage dropped right down to idle the moment I deleted the nested text boxes.
Altogether, this leads me to conclude that the “Facet (Odd Page)” footer template in Word 2013 is the source of my issue. Specifically, I believe that the use of nested text boxes in this template causes Word’s interactions with the .Net 4.5 WPF to go a
bit nuts, as evidenced by the infinite loop of request for the non-existent “Avalon.Graphics” WPF registry key I mentioned previously.
It would be nice to see some feedback on this one, Microsoft people, if only to know if this is actually a general issue or is specific to my document!
Thanks, Chris

High CPU usage, Live Ultra for Notebooks

I've been using the Live Ultra for Notebooks for a while, and it has consistently high CPU usage. It breaks down to about 50-60% for the driver (V0070Vid.sys thread, in the "System" process) and then a bit more (+5%) for DPC's. Combined with the host application (Skype, 25% CPU) means the whole thing essentially takes over my CPU.
Is this typical CPU usage for this webcam? I've used other ones, and I seem to remember that CPU usage was a lot lower. I have this problem on 2 different computers.
AMD Sempron 300+
GB Ram
Windows 2000 SP4
Please post what webcam, CPU, OS, and about how much CPU % your webcam takes. I'd like to see if these results are normal. Thanks.

I also have a Toshiba laptop with Vista Home Basic. I tried to install the "BETA" Vista drivers for this camera (VF0070) and it says the driver is only for Vista 32-bit and 64-bit. Is there a solution to this? Should I just return this and go buy a Logitech instead?

High cpu usage for garbage collection (uptime vs total gc time)

Hi Team,
We have a very high cpu usage issue in the production.
When we restart the server, the cpu idle time would be around 95% and it comes down as days goes by. Today idle cpu is 30% and it is just 6th day after the server restart.
Environemnt details:
Jrockit version:
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_05-b04)
BEA WebLogic JRockit(TM) 1.4.2_05 JVM R24.4.0-1 (build ari-38120-20041118-1131-linux-ia32, Native Threads, GC strategy: parallel)
Gc Algorithm: JRockit Garbage Collection System currently running strategy: Single generational, parallel mark, parallel sweep
Number Of Processors: 4
Max Heap Size: 1073741824
Total Garbage Collection Time: 21:43:56.5
Uptime: 114:33:4.1
Total Garbage Collection Count: 420872
Total Number Of Threads: 198
Number Of Daemon Threads: 191
Can you guys please tell me what would be problem in the server which causing the high cpu usage?
One more thing I would like to know is that why the total number of threads is 198 when we specified the Executor pool size as 25? I agree that weblogic would create some threads for its maintenance but around 160 threads!!! something is wrong I guess.
Santhosh.

Hi,
I'm having a similar problem, but haven't been able to resolve it yet. Troubleshooting is made even harder by the fact that this is only happening on our production server, and I've been unable to reproduce it in the lab.
I'll post whatever findings I have and hopefully we'll be able to find a solution with the help of BEA engineers.
In my case, I have a stand-alone Tomcat server that runs fine for about 1-2 days, and then the JVM suddenly starts using more CPU, and as a result, the server load shoots up (normal CPU utilization is ~5% but eventually goes up to ~95%; load goes from 0.1 to 4+).
What I have found so far is that this corresponds to increased GC activity.
Let me list my environment specs before I proceed, though:
CPU: Dual Xeon 3.06GHz
RAM: 2GB
OS: RHEL4.4 (2.6.9-42.0.2.ELsmp)
JVM build 1.5.0_03-b07 (BEA JRockit(R) (build dra-45238-20050523-2008-linux-ia32, R25.2.0-28))

So, I'm running with the default GC strategy which lets the GC pick the most suitable approach (single space or generational). It seems to switch to generational almost immediately and runs well - most GC runs are in the nursery, and only once in a while it goes through the older space.
Now, if you look at [Sun Oct 22 02:50:27 2006], that's when everything changes. GC starts running every second (later on it's running 3 times a second) doing huge sweeps. It never goes through the nursery again, although the strategy is still generational.
It's all downhill from this point on, and it's a matter of hours (maybe a day) before we restart the server.
I guess my only question is: What would cause such GC behavior?
I would appreciate your ideas/comments!
Thanks,
Tenyo

CF 10 sp 12 Enterprise high CPU usage hangs services, 2012 server on 2012 Hyper-V host

The last 2 days - my [removed link] CF site has suffered from high CPU usage (on and off) that stops functionality.
This will last several minutes then suddenly the high usage stops a few minute later the high cpu usage starts again.
I don't have any scheduled processes allowed to run.
Restarting the coldfusion service during a high CPS incident - the cpu usage just picks up where it left off when restarted.
I have assigned 4 CPUs (normal) or 8CPUs (as a test) to the VM and I get the same high CPU then low usage. This is a fresh install several months ago on a new VM.
I'd like some Adobe support on this issue but can't seem to find the contact phone number.
This series of high and low cpu usage first started Monday AM about midnight until 7:00 AM Tuesday was quiet and Wednesday this AM I'm having the same issues.
Ideas?
Update: While waiting for this to post - the high CPU usage started again and this time I stopped and restarted the Jetty service ... and the CPU usage went away...
Update: the high cpu started again and a restart of the jetty service didn't help --- neither did the .net service restart... the cf10 application service did stop the high usage...

Thank you,

Hi Gopi,
Check out Tim's reply and check for ur Java stack settings,
Extended Memory parameters
<i>The bottom line for J stacks is to keep everything in memory and out of swap. </i>
Other tips:
- u may try clearing folder usr\sap\<SID>\DVEBMGS00\j2ee\cluster\server0\apps
- try increasing virtual memory
- increase heap size

Safari 3.03 for Mac has high CPU usage usually above 70%

I look at the Activity Monitor and it shows Safari using a lot of CPU % around 70 % and some times near 100%

This High CPU usage is also a problem that has just started recently on my G4/667/1.5Gig Ram with a "Giga" 1.33GHz upgrade running System 10.4.10. My machine has been wonderful for years with this processor. I'm running Safari 2.0.4. When i did the last upgrades to my software I started having some real bad behavior from my mac. High CPU usage in safari (80-98%) for 3-5 minutes then normal like now I'm at 6-10% (Normal)as I type this in Safari. Safari is crashing when I try to open the Apple in store training site! Mail was crashing on my wife's login not mine though. Throwing out her mail Prefs fixed that. The Upgrades that seem to trigger this are Java for Mac OS 10.4 Release 6, Quick Time 7.3.1, GarageBand 4.1.1, iPhoto Update, iTunes 7.5. It sure feels like that last set of upgrades has made a mess of my mac. I suspect the Java update. How do I fix this mess???? [email protected]

BizTalk 2013 SFTP adapter not polling

Hi,
I am trying to poll some files from an SFTP location. I have configured my SFTP Receive Location on the BizTalk Server 2013. However I do not see any polling happening.
I have a BizTalk Server 2006 R2 environment from where I have configured the polling from the same location (this is ofcourse stopped when using the BizTalk 2013). From here, the polling is happening fine (bLogical sftp adapter).
Can you please let me know if I am missing any other steps apart from the RL configuration.
Regards,
Ujjwal

Though you have been using SFTP process with your BizTalk 2006 environment, your new BizTalk server may have new IP and new configurations. So ensure the SFTP server where
you’re trying to receive the files from allow this new server.
First try to use any SFTP client tools like
FileZilla or
WinSCP and see whether you can connect to your SFTP server. This would help you to solve some of the access issues.
Ensure your IP (external IP) is not blocked by your SFTP server. If any firewall is involved between, check this firewall is not blocking the access.
Also ensure that values you give while configuring the Security section of the Receive Location is correct. Most of the issues around the SFTP adapter trying to receive the
files are Firewall issue, Security properties configuration.
Also check
this SFTP adapter article from TechNet Wiki for more help..

Biztalk 2013 SFTP Adapter Properties

Hello All,
In Biztalk 2010, some applications use the On Receive After property in the SSHFTP adapter to remove the file after receive. How can this be done in SFTP in the Biztalk 2013.Any help is greatly appreciated.
Thanks

Sorry I don't get your point. By default files would be deleted/removed once it’s been received/downloaded. The problem what I have seen is some issue when dealing
with read-only files. In future enhancement to this adapter we may except feature like “Delete After Download” and “Enable Timestamp comparison” properties as happened in FTP adapter.

BizTalkServer 2010 SFTP Adapter from CodePlex - Configuring send and receive locations with SSH public and private keys

Hi there,
I am looking for step by step instrcutions on how to configure SFTP Codeplex adapter for both receive and send ports.
Out business partner with whom we push/poll the files from wants us to use SSH encryption/decryption etc.
Just wondering if the following functionality is supported in Codeplex SFTP adatper without having to write any code.
Appreciate if there is manaul to do this for SFTP. BTW I do have all the our public and private keys and business partners Public key for configuring.
For Send port: 1. we would need to encrypt the file with our business partners public key
                      2. sign the file with our private key.
                      3. Send the file through to SSH client which eventually transfers to Remote server.
Receive port:   1. Connect to SSH Server with SSH-2 key and receive the file
                      2. Verify the file's digital signature agaisnt the Business partners PGP public key
                      3. Decrypt the file using our PGP Public key
Thanks in advance

Yes it is supported.
You can find its documentation in this link
You can find section X.509 Certificate Identity Keys
You can set public and private key in property SSH Identity thumbprint of send and receive port
I prefer to test it using client tool like
FileZilla or WinSCP then test it using sftp adapter
