Performance of UDP Receiver during high load
Hello All,
I have the following problem and hopefully somebody can help me with this.
Our Application, SIP Proxy, is multi-threaded and this is the way we run it.
We have a UDPReceiver Thread that listens on a particular port. We have a ThreadPoolManager that has 50 Worker threads that are started when the SIP Proxy is brought up. These threads follow the wait-notify mechanism. When we get a packet ( in UDPReceiver),we add the packet to a Vector and notify the threads ( not notifyAll). The thread that is notified picks up the first job in the vector. If there are no jobs in the vectors, the workers all wait on the synchronized object.
So far no issues. Everything works fine when there is reasonable load. But when I reach a certain load I see UDP packets getting dropped (netstat -s -v 1 | grep udpInOverflows in T2000). The CPU utilization at this point is only 40%.)
I face the same packet drop issue in Linux as well. I analyzed the problem and this is what I found out.
Sometimes all the Workers are busy and UDP Receiver adds the jobs to the Vectors and there atleast 300 of these jobs in the queue ( Normally this would be 1 or 2). So when the Workers finish their existing job, they take the next one if there is any. Since there are 300+ jobs, the Workers (50 of them) pick their job. This is continuous till all the jobs in the queue are complete. Now I believe the UDP Receiver thread is not getting a chance to execute during this time
and hence the UDP buffer overflows and we get packet drops ( I have done all the OS tuning to increase the receive buffer etc).
I set a higher priority to the UDP Receiver Thread but still the same thing happened).. What is really puzzling me, how come this
thread is starved for CPU if it shows as only 40% in prstat?
Have any of you faced similar problems and if so how did you fix it?
I can paste code snippets if need be.
Thanks in advance

We do have a similar setup to this. I think I would
try to determine what the best case max throughput
you can handle, by disconnecting the receiver from
the queuing and worker thread machinery and just let
it count how many packets it can copy into a buffer
and throw out. This will allow you to get a better
idea of what effect thread contention is having on
your setup.Hi,
Thanks for the quick response. I had done what you have suggested when I was trying out different combinations. The number of workers are something we have a control over at runtime and to ensure that there are no jobs being processed I set the Worker Count at '0'. This correlates to your suggestion. When I do this, there are no packet drops at even very high packet rate. ( Ofcourse the Vector keeps growing since there are no Workers to process it) and eventually I ran out of Memory.
So as far as I can see our UDP Receiver is Ok. So it basically comes down to how do I make sure that UDP Receiver always get top priority?
Have you faced this problem at all or is there is a threshold where you see this problem?
Thanks again
Gokul

Regards,
BaaasssiFirst, compiler and system messages are hard to read unless you enclose them in "code" blocks. The Forum software otherwise interprets some character sequences as formatting directives. But I was able to puzzle out the actual mangled names of functions.
You appear to have hit the STLport default-allocator bottleneck. If multiple threads are frequently allocating and deallocating library objects (like strings), they block one another via a spin lock. Although the STLport source code has some alternative allocators, they don't seem to work well.
Some alternatives:
1. Try another implementation of the C++ Standard library, such as Apache stdcxx
[http://stdcxx.apache.org/]
Refer to the C++ Users Guide section 12.7 "Replacing the C++ Standard Library".
2. Write or find a replacement allocator, and use it explicitly throughout your code instead of the default allocator.
3. See whether you can reduce the number of actual object allocations and deallocations by managing objects on your own free list. -
Strange Oracle Behaviour - only month end or high load periods
Hi SAP Gurus
In one of our systems I am expreriencing a strange behaviour from Oracle, in that it seems to be in reconnect, but yet it is not, it resets and carries on but do produce Dump and SM21 log messages, the dump is not really helpfull as it is the same dump but with different program everytime.
I have looked in oracle alert log and found no event tying back to the SM21 log message or dump.
The following is what I found in the developer trace of one of these insident, but there are many, about 125 - 200 for the day during high load:

Performance Bottleneck at HIgh Loads
Hi,
We are currently load testing our web application and have been facing an issue that has ben bothering us for sometime now.
If we load test the application at high load for sustained amounts of time, (around 2 hours), the performance suddenly dips to Zero hits/sec, Nothing is processed , no output generated. It seems as though all the processes some how are waiting for a resource to get free.After sometime the performance goes up again and again there is a race condition because of which the performance goes down again. Here on the dipping becomes highly erratic.
We are trying to find out if this is a known bug with the oracle jdbc driver. "oracle.jdbc.driver.OracleDriver" .
Would appreciate if anybody could provide any inputs as to why this is happening and how we could alleviate the situation.
Thanks in advance.
DeepanjanHi I vaguely remember something like this.... but I thought it typically occurred during lots of heavy insert/update activity
which version of the jdbc drivers are you using.... are you using thin/thick
Have you checked the SQL or the database to determine whether any locks are blocking activity or whether you have large database wait issues....

Any answers?????Hi,
I have a similar issue on ODSI 10gR3 (WLS 10.3). I am having stuck threads - but, in my case it is clear that the database is down (not at the startup)
Here is some more info:
1. Test Connections On Reserve - Enabled
2. Default values for other parameters
Using Oracle thin driver for the connection pool "MyPool" -
./wlserver_10.3/server/lib/ojdbc6.jar
My question is:
1. How do I avoid the stuck thread caused when the database is down? During peak load, the stuck threads are causing some service requests to fail.
I did my homework and the closest option I could find is set the statementTimeout (which is set currently to the default value of -1 i.e. never timeout). Oracle documentation (http://www.oracle.com/technology/software/tech/java/sqlj_jdbc/htdocs/111070_readme.html) says that the ojdbc6.jar supports setQueryTimeout() method.
Is there any better way to attack this problem?

Oracle ODBC - Internal Error - unable to initialize NLS during driver load
I'm having some trouble with my ODBC connections which I hope someone can please help me with!
About 6 weeks ago all was working as normal.
As far as I know there have been no updates to the ORacle DB, the Windows XP operating system or the ODBC Drivers.
Today when I opened access and visual case 2 to connect to Oracle I was at first greeted with a:
unable to connect SQLState=IM004 SQL_HANDLE_ENV
error. ODBC also kept crashing.
I restarted the computer and was confronted with a different error:
odbc SQLSTate 08004 ORA 12154 TNS could not resolve the connect identifier specified
I was able to fix this error by setting the environment variable TNS_ADMIN in windows xp environment variables. I'm extremely confused about how this happened though as it was working and I don't think anything has changed.
I was then able to connect to the database via Microsoft Access but when I opened Visual Case 2 and tried to make an update, I was confronted with the following error:
Oracle ODBC Driver - internal error - unable to initialize NLS during driver load
I looked in the registry at:
HKEY_LOCAL_MACHINE\SOFTWARE\Oracle\KEY_OraClient10g_home1
HKEY_LOCAL_MACHINE\SOFTWARE\Oracle\KEY_OraClient10g_home2
HKEY_LOCAL_MACHINE\SOFTWARE\Oracle\KEY_OraDb10g_home1
and NLS_LANG was set to "AMERICAN_AMERICA.WE8MSWIN1252" in all 3 places.
(Though KEY_OraClient10g_home2 only had 4 entries as opposed to KEY_OraClient10g_home1's 13 entries)...
Since I made those changes I can no longer connect through Access.
I just receive a ODBC - connection to 'xxx' failed
Advice greatly appreciated!!!!
Edited by: user11150264 on Aug 25, 2009 10:21 PMActually it sort of does...
I switched the ODBC connection to use instant client and now it's all working again.
The biggest mystery is what changed to make it suddenly stop working the old way... -

BernardAll,
It appears that the page Javascript maximum limit size was reached. The error stopped appearing after some of the page Javascript code was removed out to Application Static Files. I wonder if there exists any "direct" indicator by the system whenever the size limit has been reached?
Again, the run error only occurred when the page was loaded in "Debug" mode.

Lock Object error during batch load
Batch load was delayed about an hour. First error message in the Server Log said "Object is already locked by user""Error 1053010 processing request [Lock Object]-Disconnecting"Then it went through a series of "Object locked by user admin" and "received client request: create Temporary Object(from user admin)"It did this several times until connection.Although from time to time we have had problems with Objects getting locked and preventing maintenance in the Application Manager. This is the first time that is has prevented a batch load. Does anyone know what could have triggered this during the load process?
This happened to us a lot, I think it's due to people opening objects, then letting their session time out, leaving a phantom lock.We solved the problem by calling the UNLOCKOBJECT function before any dimbuilds. 99.9% of the time this raises an error, "..object x is not locked..", but the rare time that the otl is inadvertently locked, it prevents the script from failing.<br><br>HTH,<br><br>Jeff McAhren<br>Dallas, Texas<br><br>ex to unlock the outline for app/db flash:<br><br>UNLOCKOBJECT 1, "FLASH" "FLASH" "FLASH"

Turning off sleep mode during high CPU usage
There isn't option to prevent going to sleep mode during high CPU or network usage. This is not professional for serious work like 3D rendering, video montage, downloading or sending large files. Windows is going to sleep during performing serious tasks.
Setting different sleep mode values every time is no way because we didn't know how long these tasks will running.There isn't option to prevent going to sleep mode during high CPU or network usage.

2008 R2/ Win7 Offline Files Sync causing High Load on server
Hi Everyone,
I have recently been investigating extremely high CPU Usage from the System Process on my company's main File Cluster.
We managed to track SRV2.sys Threads causing high CPU load within the system process, but was having issues identifying why this was the case.
As per Microsoft's direction via support call, we have installed the latest SRV2.sys Hotfixes, but this does not appear to have allivated the issue we are experiencing. We have also added more CPU and Memory into both nodes, which has not helped either.
We have since managed to create a system dump and is being sent to MS Support for analysis.
I have noticed the following that appears to happen on our cluster:
Whenever our CAD/Design department run certain functions within their apps running on a windows 7 client (apps include MicroStation, Revit, AutoCAD etc) we see a massive spike and flatline of the system process.
We found several users with Windows 7 clients that have Configured Offline File to sync an entire Network Volume (some volumes are 2TB Plus, so would never fit on a users computer anyway, i was quite shocked when I found this). How we spotted this was through
Resource Monitor, the System Process was trolling through all the folders and files in a given volume (it was "reading every single folder). Now, while this was the system process, we could identify the user by using the Open Files view in Server Manager's
Share and Storage Management tool.
I have done a fair bit of research and found that a lot of CAD/Drawing applications in the market have issues with using SMB2 (srv2.sys). When reviewing the products that we use, I noticed that a lot of these products actually recommended disabling SMB2
and reverting to SMB1 on File Server and/or the clients.
I have gone down the path of disabling SMB2 on all Windows 7 clients that have these CAD Applications installed to assist with lowering the load (our other options are to potentially shift the CAD Volumes off our main file cluster to further isolation these
performance issues we have been experiencing.) We will be testing this again tomorrow to confirm that the issue is resolved when mass amounts of CAD users access data on these volumes via their CAD Application.
We only noticed the issue with Offline Files today with trying to sync an ENTIRE Volume. My questions are:
Should Offline File sync's really cause this much load on a File Server?
Would the the size of the volume the sync is trying to complete create this additional load within the system process?
What is the industry considered "Best Practice" regarding Offline Files setup for Volumes which could have up to 1000+ users attached? (My personal opinion is that Offline Files should only be sync of user "Personal/Home" Folders
as they users themselves have a 1 to 1 relationship with this data.)
Is there an easier way to identify what users have Offline Files enabled and "actually being used" (from my understanding, Sync Center and Offline Files are enabled by default, but you obviously have to add the folders/drives you wish to sync)?
If I disable the ability for Offline Files on the volumes, what will the user experience be when/if they try to sync their offline files config after this has been disabled on the volume?
Hoping for some guidance regarding this setup with Offline Files.
Thanks in Advance!
SimonHi Everyone,
Just thought I would give an update on this.
While we're still deploying http://support.microsoft.com/kb/2733363/en-us to
the remainder of our Windows 7 SP1 fleet, according to some Network Traces and XPerf that were sent to MS Support, it looks as though the issu with the Offline Files is now resolved.
However, we are still having some issues with High CPU with the System Process in particular. Upon review of the traces, they have found a lot of ABE related traffic, leading them to believe that the issue may also be caused by ABE Access on our File Cluster.
We already have the required hotfix for ABE on 2008 R2 installed (please see
http://support.microsoft.com/kb/2732618/en-us), although we have it set to a certain value that MS believe may be too high. Our current value is set to "5", as that is the lowest level of any type of permission is set (i.e. where the lowest level of inheritance
is broken).
I think I will mark this as resolved regarding the Offline Files issue (as it did resolve the problem with the Offline Files)...
Fingers crossed we can identify the rest of the high load within the System Process!!! -
Replacing / Compiling Database Triggers in a HA/High Load system
Hi there,
My collegue has just asked me if downtime needs to be scheduled to replace an After IUD Database trigger where I've made a minor change.
If this were a package or procedure, the answer would be an obvious yes, as I'd be wary of my users getting the dreaded: ORA-04068... State of Package has been disguarded.
What about when working with database triggers?
If the trigger is firing at the same time that I perform my Create or Replace Trigger DDL, will everything fall into a screaming heap?
Notes:
Oracle 10g R2 db.
High DML rates on the table that the After IUD Trigger is 'attached' to.
It's a near certainty that when the Create or Replace Trigger DDL runs, the trigger will be active at the time.
The Trigger is 'simple' in that it's use: is to call a DB package with some of the :new values as params.
+(I'm happy to rtfm - if someone can tell me where!!)+
Cheers -
Ron MarksIf this were a package or procedure, the answer would be an obvious yes, as I'd be wary of my users getting the dreaded: ORA-04068... State of Package has been disguarded.Not true. This exception is thrown only if sessions have some state represented in package variables. If there is no associated session state, then no exception would be thrown after recompile.
If the trigger is firing at the same time that I perform my Create or Replace Trigger DDL, will everything fall into a screaming heap?You'll wait - to lock an object in library cache which represents your trigger. Not sure if this would require a library cache lock on underlying table, but I would guess that it is required. BTW, locking a table would make no any sense: CREATE TRIGGER is a DDL, which means before it began it issues a COMMIT => all locks are released, and it is quite possible that a TM lock for CREATE TRIGGER won't be acquired since resource would be busy.
Oracle 11gR2 claims to address problems of application upgrades on a high-load environments with a feature called "Editions" (not a good name - try to find something about it via Google...) -
Sync messages failed due to high load
Hi!
On our test system we had a very high load of async messages for 3 - 4 hours. The async messages were processed successfully but all sync messages failed during this time frame! As soon as the high load of async messages stopped, the sync messages started executing successfully again.
Has anybody also experienced this kind of problem and what can be done to avoid this issue? Thanks for any input and suggestions.
Regards, Tanjahey Tanja,
i had a similar issue when testing the box with Load runner, that a simple sync scenario fails when the size of payload or attachment is high, the thing that i did is just increased the virtual memory ,
You can also check the trace files to figure out problem ?
This might not be a definitive answer , hope this helps,

Safari causes system freeze during page load
Description:
I've been trying to figure this one out for a while now (about 2 weeks), without any luck. I've tried reading a couple of threads describing similar problems, but it looks like I've got something else going on here seeing as it affect the entire system. I appreciate any suggestion!
When a window in Safari is open and you're loading a page, it sometimes (almost always) causes a system freeze. Any action performed on any input device within OSX while a page is loading gets delayed by 5-20 seconds. Anything from right-clicking, to opening a new tab in Safari, to navigating to a new folder in Finder.... literally anything. The actual loading of the page is also affected by this. So when I click a link, the page becomes white and the system stalls. After X seconds, the system resumes and the page is displayed fully loaded. Once the page is loaded, everything is back to normal. I can just leave the Safari-window open without anything happening. It's just during the loading of a page.
Using the mouse to move and switch between open windows are the only actions I seem to be able to perform during the system freeze.
When it doesn't cause a system-wide freeze, it will still take forever for any page to load. Which isn't a problem in any other browser and I've never had any speed issues in general on any device.
What I know for sure is that I can solve the problem by closing all open Safari-tabs and windows or closing the app completely, and use Chrome instead. But I do like Safari, so I hope there's another way to fix this.
I should also note that I've made no changes to the system for many weeks now, other than installing whatever updates might have been available on the App Store.
What I've tried within Safari:
- program restart
- reset settings (every option checked)
- disable and remove extensions (only had one installed, LiveReload for Adobe Brackets)
- empty cache
- delete cookies
What I've tried within OSX:
- system restart
- complete OSX-recovery
- activity monitor (CPU, HDD and RAM always within normal values during all of this)
- checked HDD (successfull)
- checked internet-connection (got 50Mbit/s connection, no speed issues, checked on multiple devices)
- tried other browsers (Chrome (OSX) and IE (Win 7, Parallels) both run smoothly)
- turned off IPv6 in terminal (based on a suggestion here at the forums)
- disabled iCloud-sync
- disabled Dropbox
- probably a couple of other things i can't remember right nowSo... I finally fixed it.
In addition to the things I mentioned I tried, I also checked if it could be malware-related. It wasnt. I then checked if it was just affecting my user-account or OSX globally. I created a new account and Safari ran perfectly. I therefore assumed it had to be something in my library-folder.
I deleted just about any mention of Safari in the Library-folder (the visible one) and just to be absolutely sure, I deleted the Contents-folder inside Safari.app in the Applications-folder. I then downloaded and installed Safari 7.0.3. Everything runs smooth now.
