Weblogic.kernel.Default' has become "unstuck"
Running WL 8.1 sp2 on Windows XP Pro. with 2Gb. of memory.
I have an EJB 2.0 CMP application accessing an Oracle 8.1.7 database.
I retrieve 1,440 rows and then start processing each row, and submitt "Jobs" to
a third party product using WebServices.
It only had 3 rows remaining to process when I got;
<03-Feb-2004 13:45:47 o'clock GMT> <Info> <WebLogicServer> <BEA-000339> <ExecuteThread:
'10' for queue: 'weblogic.kernel.Default' has become "unstuck".>
Any pointers?
Thanks.

Hi,
When I invoke this JSP, the servlet gets the request and sends a reply, but the
JSP never finishes. The connection isn't dropped, the browser icon keeps spinning,
as if it is still trying to load the page. But nothing ever happens. After more
than 10 minutes or more I get a message in the stdout of weblogic server saying
something about a stuck thread.
Note: The JSP sends an SQL statement to Servlet, which in turn calls a DAO class
to execute the sql and return the result back to Servlet. i m using Weblogic 8.1
Please help me as it is very urgent. Production Problem. It occurs randomly.Hi,
It looks like you have an AXIS webservice based Application deployed on the Server which has the following Method: com.test.ws.Stub.getInfo(ClientStub.java:813) the call to that method is happening over HTTPS protocol. getInfo() method might be trying to read a Large amount of Information from some sources which may be taking more than 600 Seconds. 600 Seconds is the Default Duration for WebLogic Threads after which the WebLogic Marks those Threads as Stuck Thread.
So we need to debug the data which is being fetch by the Application code at the following line com.test.ws.Stub.getInfo(ClientStub.java:813)...It might be possible that sometimes while execution of the above method it might be processing or asking for a Large amount of Data which is more than the Configured Thread Timeout period.
As well as it looks like the Above code is trying to get some data from a remote Server/JVM beacuse it is getting stuck while reading Data from a Socket:
java.net.SocketInputStream.socketRead0(Native Method)
java.net.SocketInputStream.read(SocketInputStream.java:129)
So u need to check the Other end also from where the code is actually trying to get the Information or Data ....*com.test.ws.Stub.getInfo(ClientStub.java:813)*
Developers can easily findout what the "ClientStub.java" classes method getInfo() is actually doing.
Thanks

ExecuteThread for queue: 'weblogic.kernel.Default' stuck
Hello!
I have web application deployed on WebLogic 8.1 SP 4 cluster which is seriously loaded (~30 concurrent users) and periodically I get such messages wrote to log file:
<Apr 2, 2007 10:11:54 AM EDT> <Error> <WebLogicServer> <BEA-000337> <ExecuteThread: '51' for queue: 'weblogic.kernel.Default' has been busy for "233" seconds working on the request "Http Request: /myurl/some_jsp.jsp", which is more than the configured time (StuckThreadMaxTime) of "180" seconds.>
As far as I could find from BEA documentation these messages mean that some threads (it is ExecuteThread#51 here) are runned for too long time.
I've made a thread dump and found that for a few (10-15min) thread is doing the same work:
"ExecuteThread: '51' for queue: 'weblogic.kernel.Default'" daemon prio=1 tid=0x6ca004b8 nid=0x3094 runnable [0x6c9fe000..0x6c9ff868]

As you can see, thread is just writing to the socket for 10-15 minutes!!!
Can you help with some suggestions? Can this problem occure because of huge overloading to the server?
Thanks for all your responses.

Weblogic.kernel.Default not using all threads
We are running weblogic 8.1 sp4 on HP Tru64 5.1.
We have an admin server and 3 managed servers in a cluster.
When monitoring the weblogic.kernal.Default execute threads through the weblogic console, threads 0 to 15 have zero total requests, and the user is marked '<WLS Kernal>'. Threads 16 to 24 share the entire workload with thousands of requests shared between them, and have user marked as 'n/a' (when idle).
I have done a thread dump, and threads 0 to 15 just seem to be idle.
This is the case for the admin server, server 1 and server 3. But server 2 actually shows all threads 0 to 24 as sharing the workload, and the user is 'n/a' for all threads.
Is there a reason for this?
Below is a snippet of the thread dump showing a thread that is has user '<WLS Kernel>':

high usage is not necessarily high efficiency. often the opposite.
Windows 7 seems to be optimized for multi-core thanks to a lot of reworking. Intel wants and knows it isn't possible to hand code, that the hardware has to be smarter, too. But the OS has a job, and right now I don't think it does it properly. Or handle memory.
Gulftown's 12MB cache will help, and over all should be 20% more efficient doing its work.
With dual processors, and it doesn't look like there are two quick path bridges, data shuffling has led to memory thrashing. Use to be page thrashing with not enough memory. Then core thrashing but having the cores, but not integrated (2008 is often touted as being greatest design so far, but it was FOUR dual-cores, 2009 was the first with a processor that really was new design and (native) 4-core.
One core should be owned by the OS so it is always available for its own work and housekeeping.
The iTunes audio bug last year showed how damaging and not to implement code and how a thread could usurp processing and add a high cpu temperature while basically doing nothing, sort of a denial of service attack on the processor - those 80*C temps people had.
All those new technology features under development and not like OpenCL, GCD and even OpenGL are tested, mature but rather 1.0 foundation for the future. A year ahead of readiness. -
Weblogic.kernel.Default Queue problems
Hello,
We have a problem with our Production server where the threads in the weblogic.kernel.Default queue simply hang up .
The Stuck Thread Max Time and the Stuck Thread Timer Interval have been configured for 60s but many times the threads simply dont get UnStuck. :(
Is there anyway to kill the threads without restarting the Server itself ???
thanks,
sgWe generated varios thread dumps and we found a number of threads in "locked" state with LDAP :
"ExecuteThread: '15' for queue: 'weblogic.kernel.Default'" daemon pri
at java.lang.Object.wait(Native Method)
- waiting on <73e5b9d0> (a com.sun.jndi.ldap.LdapRequest)
at com.sun.jndi.ldap.Connection.readReply(Connection.java:418)
- locked <73e5b9d0> (a com.sun.jndi.ldap.LdapRequest)
at com.sun.jndi.ldap.LdapClient.getSearchReply(LdapClient.java:701)
The thing is, there is nothing wrong with LDAP. We are simulating new requests to LDAP and LDAP is responding is less than 1 s ! But the thread dump indicates the threads are hung in LDAP :(
The LDAP admin did a thorough check and came up with nothing... Is there anything else I can check for ?
thnx,

you should check your configuration to see if you have done it right and then you should check your application and the properties settings in the controls to ensure they are right. -
Why are the weblogic.kernel.Default Execute Threads used by WLS Kernel
In my Admin Console, it's displaying 10 out of the 15 weblogic.kernel.Default Execute Threads are used by the WLS Kernel user. The total requests column for these threads are showing 0. The other 5 threads are showing 20K to 40K requests. Why is the WLS Kernel users hogging these threads and not allowing the applications to use them?
Hi,
As work enters a WebLogic Server, it is placed in an execute queue. This work is then assigned to a thread within the queue that performs the work.
By default, a new server instance is configured with a default execute queue, weblogic.kernel.default, that contains 15 threads.
Go through the following link and find the usefull information on this issue.

I have two servers, serverOne and serverTwo, that are running different applications on WL815, Solaris 10, x86 platform.
Both have ThreadCount=25, Threads Max=400, and Threads Increase = 15.
1. I have noticed when I monitor the weblogic.kernel.Default queue, no matter how much the load is on the server, there are no more than 25 thread in the queue. Why is it?
2. On serverOne, only 6 threads out of the 25 are being used by <WLS Kernel> and the rest of the threads are allocated to the applications. However, on serverTwo, about 19 threads out of 25 are being used by <WLS Kernel>, and ther rest are used by the application. FYI, there are 4 application queues deployed on serverTwo. What is the reason for so many threads being used by <WLS Kernel> on ServerTwo?
Thanks for all your answers in advance!Can you post the complete stacktrace? That may yield a clue.

2. If you don't already have a current backup, back up all data before doing anything else. The backup is necessary on general principle, not because of anything in the test procedure. There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
3. Below are instructions to run a UNIX shell script, a type of program. All it does is to collect information about the state of the computer. That information goes nowhere unless you choose to share it. However, you should be cautious about running any kind of program (not just a shell script) at the request of a stranger on a public message board. If you have doubts, search this site for other discussions in which this procedure has been followed without any report of ill effects. If you can't satisfy yourself that the instructions are safe, don't follow them. Ask for other options.
Here's a summary of what you need to do, if you choose to proceed: Copy a line of text from this web page into the window of another application. Wait for the script to run. It usually takes a few minutes. Then paste the results, which will have been copied automatically, back into a reply on this page. The sequence is: copy, paste, wait, paste again. Details follow.
4. You may have started the computer in "safe" mode. Preferably, these steps should be taken in “normal” mode. If the system is now in safe mode and works well enough in normal mode to run the test, restart as usual. If you can only test in safe mode, do that.
5. If you have more than one user, and the one affected by the problem is not an administrator, then please run the test twice: once while logged in as the affected user, and once as an administrator. The results may be different. The user that is created automatically on a new computer when you start it for the first time is an administrator. If you can't log in as an administrator, test as the affected user. Most personal Macs have only one user, and in that case this section doesn’t apply. Don't log in as root.
6. The script is a single long line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, though you may not see all of it in the browser window, and you can then copy it. If you try to select the line by dragging across the part you can see, you won't get all of it.
Triple-click anywhere in the line of text below on this page to select it:

Copy the selected text to the Clipboard by pressing the key combination command-C.
7. Launch the built-in Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Click anywhere in the Terminal window and paste (command-V). The text you pasted should vanish immediately. If it doesn't, press the return key.
8. If you see an error message in the Terminal window such as "syntax error," enter
exec bash
and press return. Then paste the script again.
9. If you're logged in as an administrator, you'll be prompted for your login password. Nothing will be displayed when you type it. You will not see the usual dots in place of typed characters. Make sure caps lock is off. Type carefully and then press return. You may get a one-time warning to be careful. If you make three failed attempts to enter the password, the test will run anyway, but it will produce less information. In most cases, the difference is not important. If you don't know the password, or if you prefer not to enter it, press the key combination control-C or just press return three times at the password prompt. Again, the script will still run.
If you're not logged in as an administrator, you won't be prompted for a password. The test will still run. It just won't do anything that requires administrator privileges.
10. The test may take a few minutes to run, depending on how many files you have and the speed of the computer. A computer that's abnormally slow may take longer to run the test. While it's running, there will be nothing in the Terminal window and no indication of progress. Wait for the line
[Process completed]
to appear. If you don't see it within half an hour or so, the test probably won't complete in a reasonable time. In that case, close the Terminal window and report the results. No harm will be done.
11. When the test is complete, quit Terminal. The results will have been copied to the Clipboard automatically. They are not shown in the Terminal window. Please don't copy anything from there. All you have to do is start a reply to this comment and then paste by pressing command-V again.
If any private information, such as your name or email address, appears in the results, anonymize it before posting. Usually that won't be necessary.
12. When you post the results, you might see the message, "You have included content in your post that is not permitted." It means that the forum software has misidentified something in the post as a violation of the rules. If that happens, please post the test results on Pastebin, then post a link here to the page you created.
Note: This is a public forum, and others may give you advice based on the results of the test. They speak only for themselves, and I don't necessarily agree with them.

My MacBook Pro has become extremely slow
Overnight my MacBook Pro (2012) has become very slow when trying to complete any task. I have plenty of space left and have emptied my trash but the problem persists. For added detail, I did just get an iphone which may be slowing my computer down through Icloud? Also, I did try downloading a file from a program called vuze, but I have done that before with no issues. Otherwise, I havent changed or done anything out of the ordinary to bring about this issue. If you have any suggestions that would be great, thanks.
This procedure is a diagnostic test. It changes nothing, for better or worse, and therefore will not, in itself, solve your problem.
If you don't already have a current backup, back up all data before doing anything else. The backup is necessary on general principle, not because of anything in the test procedure. There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
Below are instructions to run a UNIX shell script, a type of program. All it does is to gather information about the state of your computer. That information goes nowhere unless you choose to share it on this page. However, you should be cautious about running any kind of program (not just a shell script) at the request of a stranger on a public message board. If you have doubts, search this site for other discussions in which this procedure has been followed without any report of ill effects. If you can't satisfy yourself that the instructions are safe, don't follow them.
Here's a summary of what you need to do: Copy a line of text from this web page into the window of another application. Wait about a minute. Then paste some other text, which will have been copied automatically, back into a reply on this page. The sequence is: copy, paste, wait, paste again. Details follow.
You may have started the computer in "safe" mode. Preferably, these steps should be taken in “normal” mode. If the system is now in safe mode and works well enough in normal mode to run the test, restart as usual. If you can only test in safe mode, do that.
If you have more than one user, and the one affected by the problem is not an administrator, then please run the test twice: once while logged in as the affected user, and once as an administrator. The results may be different. The user that is created automatically on a new computer when you start it for the first time is an administrator. If you can't log in as an administrator, test as the affected user. Most personal Macs have only one user, and in that case this paragraph doesn’t apply.
The script is a single long line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, though you may not see all of it in your browser, and you can then copy it. If you try to select the line by dragging across the part you can see, you won't get all of it.
Triple-click anywhere in the line of text below on this page to select it:

My internet has become very slow on Macbook Pro
I don't know what happened but since few days my internet has become very slow on all sites It takes ages for a youtube video to be played. I sometimes to refresh a page for it to appear.
Safari, Firefox and Chrome all 3 have become very slow.
I tried changing my wireless internet 3 times but all the time it is slow.
I have had my laptop for more than 3 years now.1. This procedure is a diagnostic test. It changes nothing, for better or worse, and therefore will not, in itself, solve the problem. But with the aid of the test results, the solution may take a few minutes, instead of hours or days.
Don't be put off by the complexity of these instructions. The process is much less complicated than the description. You do harder tasks with the computer all the time.
2. If you don't already have a current backup, back up all data before doing anything else. The backup is necessary on general principle, not because of anything in the test procedure. Backup is always a must, and when you're having any kind of trouble with the computer, you may be at higher than usual risk of losing data, whether you follow these instructions or not.
There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
3. Below are instructions to run a UNIX shell script, a type of program. As I wrote above, it changes nothing. It doesn't send or receive any data on the network. All it does is to generate a human-readable report on the state of the computer. That report goes nowhere unless you choose to share it. If you prefer, you can act on it yourself without disclosing the contents to me or anyone else.
You should be wondering whether you can believe me, and whether it's safe to run a program at the behest of a stranger. In general, no, it's not safe and I don't encourage it.
In this case, however, there are a couple of ways for you to decide whether the program is safe without having to trust me. First, you can read it. Unlike an application that you download and click to run, it's transparent, so anyone with the necessary skill can verify what it does.
You may not be able to understand the script yourself. But variations of the script have been posted on this website thousands of times over a period of years. The site is hosted by Apple, which does not allow it to be used to distribute harmful software. Any one of the millions of registered users could have read the script and raised the alarm if it was harmful. Then I would not be here now and you would not be reading this message.
Nevertheless, if you can't satisfy yourself that these instructions are safe, don't follow them. Ask for other options.
4. Here's a summary of what you need to do, if you choose to proceed:
☞ Copy a line of text in this window to the Clipboard.
☞ Paste into the window of another application.
☞ Wait for the test to run. It usually takes a few minutes.
☞ Paste the results, which will have been copied automatically, back into a reply on this page.
The sequence is: copy, paste, wait, paste again. You don't need to copy a second time. Details follow.
5. You may have started the computer in "safe" mode. Preferably, these steps should be taken in “normal” mode, under the conditions in which the problem is reproduced. If the system is now in safe mode and works well enough in normal mode to run the test, restart as usual. If you can only test in safe mode, do that.
6. If you have more than one user, and the one affected by the problem is not an administrator, then please run the test twice: once while logged in as the affected user, and once as an administrator. The results may be different. The user that is created automatically on a new computer when you start it for the first time is an administrator. If you can't log in as an administrator, test as the affected user. Most personal Macs have only one user, and in that case this section doesn’t apply. Don't log in as root.
7. The script is a single long line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, though you may not see all of it in the browser window, and you can then copy it. If you try to select the line by dragging across the part you can see, you won't get all of it.
Triple-click anywhere in the line of text below on this page to select it:

Copy the selected text to the Clipboard by pressing the key combination command-C.
8. Launch the built-in Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Click anywhere in the Terminal window and paste by pressing command-V. The text you pasted should vanish immediately. If it doesn't, press the return key.
9. If you see an error message in the Terminal window such as "Syntax error" or "Event not found," enter
exec bash
and press return. Then paste the script again.
10. If you're logged in as an administrator, you'll be prompted for your login password. Nothing will be displayed when you type it. You will not see the usual dots in place of typed characters. Make sure caps lock is off. Type carefully and then press return. You may get a one-time warning to be careful. If you make three failed attempts to enter the password, the test will run anyway, but it will produce less information. In most cases, the difference is not important. If you don't know the password, or if you prefer not to enter it, press the key combination control-C or just press return three times at the password prompt. Again, the script will still run.
If you're not logged in as an administrator, you won't be prompted for a password. The test will still run. It just won't do anything that requires administrator privileges.
11. The test may take a few minutes to run, depending on how many files you have and the speed of the computer. A computer that's abnormally slow may take longer to run the test. While it's running, there will be nothing in the Terminal window and no indication of progress. Wait for the line
[Process completed]
to appear. If you don't see it within half an hour or so, the test probably won't complete in a reasonable time. In that case, close the Terminal window and report what happened. No harm will be done.
12. When the test is complete, quit Terminal. The results will have been copied to the Clipboard automatically. They are not shown in the Terminal window. Please don't copy anything from there. All you have to do is start a reply to this comment and then paste by pressing command-V again.
At the top of the results, there will be a line that begins with the words "Start time." If you don't see that, but instead see a mass of gibberish, you didn't wait for the "Process completed" message to appear in the Terminal window. Please wait for it and try again.
If any private information, such as your name or email address, appears in the results, anonymize it before posting. Usually that won't be necessary.
13. When you post the results, you might see an error message on the web page: "You have included content in your post that is not permitted," or "You are not authorized to post." That's a bug in the forum software. Please post the test results on Pastebin, then post a link here to the page you created.
14. This is a public forum, and others may give you advice based on the results of the test. They speak only for themselves, and I don't necessarily agree with them.

With mavericks the computer has become slow
With mavericks the computer has become slow
Hi Pete. First time here so I'm hoping I'm doing this correctly.
I have the same problem - my applications are extrememly slow to open and shut down since I installed Mavericks. I used the Etrecheck and will past the results here.
thanks for your help.

My mac has become slow since installing mavericks iOS
Since installing the Mavericks OS my Mac has become slow and unresponsive, it freezes up all of the time and I always have to wait for the different software to load once I have clicked on the icon.
Before I installed Mavericks when I clicked on a program it opened straight away and I could use it immediatly, is any one else having this problem?
Thank youHere's your report with some comments in red:

2 GB RAM Mavericks will run with 2 GB of RAM, but it won't run well. I know the specs say 2, but 4 is a more realistic minimum for reasonable performance. You have page-outs (see the last line of the report), which means that tasks are being paged out to your virtual memory (i.e., your hard drive), because your RAM is full. The page outs might go down if you fix some of the possible problems below, and your performance might improve; if it doesn't, you might consider putting more RAM in your Mac.

First, make sure you have a good backup.
What to do about the items in green:
The items in green are third party software that may be a problem. They run all the time in the background, and thus may be making things slow. You can test this theory: try a safe boot (restart, hold down shift until you see the Apple logo). A safe boot does some diagnostic checking and then starts up without third party added-on software. If this eliminates the symptoms, then you know the problem is with a third-party item. Mac OS X: What is Safe Boot, Safe Mode?
I don't know if the green ones are a problem or not, but they are on the list of suspects, and you're going to need to do some research yourself.
The general philosophy is:
Figure out what the application is that is responsible for a particular green item.
If you can live without the application, it, uninstall it. You should uninstall the entire application that is responsible, not just the green bit. The best way is with an uninstaller from the developer of the application. If there's no uninstaller (one of the hallmarks of crapware), then an internet search may help (as in, "uninstall crapapp mac", where crapapp is the name of the software in question). After uninstalling the app, restart, see how your symptoms are, and run Etrecheck again. I am a fan of AppZapper for uninstalling apps, if there is no uninstaller from the developer. AppZapper - The uninstaller Apple forgot.
Sometimes, after you have run an uninstaller or manually uninstalled a suspect application, one of those green bits will still be on the Etrecheck report. If your Mac's symptoms have resolved, it's better to leave well enough alone and leave it there. If you must, you can try a modified Finder search to find the stubborn green bit and remove it. These system files do not show up in a default Finder or Spotlight Search.
If you can't live without this app, then at least make sure it is up to date and compatible with Mavericks.
What to do about the items in red
These are definite problems and should be fixed if they are Apple software. They should be fixed or uninstalled if they are third party developer software.
For red Apple items, I would try:
repairing your hd. Boot into your recovery partition (restart, hold down ⌘R until you see the Apple logo), and use Disk Utility to repair your hard drive. Repair permissions too while you're there. OS X: About OS X Recovery Then restart, reassess performance, and rerun Etrecheck.
If that doesn't work, I'd try Techtool, which can occasionally fix something that disk utility can't. Techtool Pro 7 Then restart, reassess performance, and rerun Etrecheck.
If that doesn't work, I'd reinstall Mavericks over your current installation. Restart, reassess, and Etrecheck.
If that doesn't work, you're looking at the nuclear option: backup your documents, erase your HD, and do a clean reinstall of Mavericks.
For red non-Apple software, I'd uninstall it and then recheck with Etrecheck. Then if you must reinstall it, make sure it's up to date and compatible with Mavericks. -
My imac has become extremely slow
Hi, I have a 4 year old 27 inch imac, running 10.10.3; it has become extremely slow to boot up, to open apps and to get online. I'm a fairly heavy user of dropbox, and I am wondering if that is the issue -- other than that I run very run of the mill apps -- itunes, word/ppt/excel/, ical, imessage, firefox and safari, adobi acrobat, some use of iphoto. Suggestions?
Hi Old Toad -- this is what I got on Etrecheck:
Problem description:
iMac is running very slow, especially when opening apps, and esp. when opening browsers. (And within browser — e.g., gmail v. slow).

My 2011 Macbook has become exceedingly slow after upgrading to Mountain Lion.
I have a 2011 Macbook which has become really slow after I upgraded to Mountain Lion in March. At first it wasn't that bad, but it's getting worse and my computer has begun to overheat even if I'm only using Google Chrome. I used to be able to keep multiple applications open at once and never closed many of them, but now if I want to get anything done I have to use the absolute minimum. My CPU has reached 86 degrees Celsius and temperatures slightly below this seem to be the average, even if I've only been on for ten minutes. It heats up VERY quickly. The fan has been operating at 2919 rpm, but it has said that for days and I don't know if this number should be changing? (I know that normal is about 2000 rpm, so I know it shouldn't be that high anyway.)
I'm currently working on cleaning out my harddrive of duplicate and unnecessary files and I plan on restoring to the default settings and backing everything up on an external harddrive... but are there other things I should be doing to speed my computer back up, like good programs to clean out my computer's temporary memory on a regular basis? The problem seems to have come on pretty fast though, so I don't know if there could be something else wrong with it and if I should take it into an Apple-approved repair place.
Also, I'm not one to illegally download/pirate things from sketchy websites, so I highly doubt a virus is the cause, especially given that Macs rarely get viruses.
Any suggestions of what to do and what programs/apps to install would be greatly appreciated! Thank you!I have a 2011 Macbook which has become really slow after I upgraded to Mountain Lion in March.
