VP UML 7.1 Hangs

General Questions/Discussions
1

Hi

I’m using version 7.1 and sometimes the application hangs and I have to kill it and relaunch it on Mac OS X.

I didn’t have this problem on the 7.0 version with evaluation licence.

I noticed I have a java process using 100% of my CPU :frowning:

Thanks

Hi Yeti,

Thanks for your post and we are sorry about this problem. May I know usually what operation it was doing while it hanged?
Also, could you please send me the vp.log file inside VPSuite/bin folder to take a look? Thanks in advance!

Best regards,
Lilian Wong

Hi, I don’t do anything special, it just appends randomely.

Here is the end on the log file I extracted (Help-About-etc), it seems I don’t have write permissions but I don’t seen any reason for VP need to write in there.
VP is set up in a multi-user Mac, we installed it in Applications, so a basic user doesn’t have any permission on it.

Hi Yeti,

Thanks for your replying. May I know you are using Java 1.6? If yes, could you please dump the thread by JVisualVM when VP-UML hangs, so our engineers can check the problem? Thanks in advance!

FYI, JVisualVM (jvisualvm.exe) is available in ${Java1.6}/bin folder. You can select the process ID of VP-UML for dumping the thread and sending the thread to us (in .txt file).

Thanks in advance!

Best regards,
Lilian Wong

Hi,
Yes, java -version gives

java version "1.6.0_15"
Java(TM) SE Runtime Environment (build 1.6.0_15-b03-219)
Java HotSpot(TM) 64-Bit Server VM (build 14.1-b02-90, mixed mode)

When I do

Kill -3 PID of the java VM

, nothing is displayed on the screen, no file seems to be created.

I’m using Mac OS Snow Leopard.

Edit : jstack returns

In this case, I had just asked to save the diagram using a shortcut (which explains the postProcessKeyEvent call).

Hangs don’t only happen on key events.

Hi Yeti,

Thanks for replying and the details. Our engineers checked the code and it’s running Java code instead of our code, and it seems not hanged.

But you mentioned the Java process consumed 100% of your CPU, this should be a dead loop. Could you please wait the application to hang and dump the thread by JVisualVM, wait for few seconds later and dump the thread again. Then repeat thread dumping few times, and save them in .txt for our engineers to check what is looping? Thanks in advance!

And may I know what step you had when it hanged before?

BTW, detailed steps for dumping thread of VP-UML:

  1. you can start JVisualVM by Terminal - open Terminal and type “jvisualvm”
  2. identify the PID of VP-UML by Activity Monitor
  3. base on the PID of VP-UML, locate corresponding Java process in JVisualVM
  4. right-click on the process of VP-UML and select Thread Dump in popup menu
  5. the thread of VP-UML process will be available (under node of VP-UML process)

Best regards,
Lilian Wong

Hi, when I right click on the process, I don’t have any “Thead dump” option, I just can do an application snapshot.

Edit, when I select the right process, the “thread dump” option isn’t enabled in the application menu.
VP UML is shown as “unknown application”

Hi Yeti,

Thanks for replying. Would you mind to capture a screenshot of

  1. Activity Monitor with process of VP-UML selected, so we can see if your process is “Intel” or “Intel (64 bit)” (you can refer to the attached image)
  2. what it shows when you right-click on the process of VP-UML

Also, would you mind to tell me what version of Mac OS X you are using, and do you use other language in VP-UML? Thanks!

Best regards,
Lilian Wong

You will find attached the activity monitor.

Nothing happens when I right click on the process.

I’m using the 10.6.1 Snow Leopard Mac OS version.

So far I just use UML.

Thanks.

Hi Yeti,

Thanks for replying. I’m sorry that I do not make my request clearly. Could you please right-click on the VP-UML process in JVisualVM so I can see what popup menus do you have (you said tehre is Thread Dump menu there)? Thanks in advance!

Best regards,
Lilian Wong

Hi,

Here are some screenshots :

As you can see, the Thread Dump option is disabled…

Hi Yeti,

Thanks for replying with the screenshot. The problem should relate to 64-bit, could you please run “VP Suite Update” to update to latest build of VP-UML (20091017) and see if the problem can be solved?

I look forward to hearing your response.

Best regards,
Lilian Wong

Hi there.

I just updated to 20091021g version, I will let you know what’s going on!

Hi Yeti,

Thanks and I look forward to hearing from you again.
