stacktrace of "out of handles"
here is the stacktrace
I haven't seen these problems during regular use of the Eclipse 4 SDKs. I presume you get this on a regular basis. Do your coworkers have the same problem? (In reply to comment #2) > I haven't seen these problems during regular use of the Eclipse 4 SDKs. I > presume you get this on a regular basis. Do your coworkers have the same > problem? Actually I'm the only one experimenting with e4. Maybe it's platform / machine-specific. I'll try this on another machine. My current machine's Java Version: 1.7.0-b147 64-bit The error occured frequently (approximately 2 times in an hour (including a reboot)), but happens a lot more, when using the resize buttons in the editor often. It seems that it does only happens when I had used resize before. I assumed that this handle error depends on the system handles and found some descriptions for "out of handles" with rcp. I'm not familiar with the handle-usage in windows with swt, but here are a few other observations using process explorer: eclipse.exe: - number of handles: around 40 - user handles: < 10 - GDI handles: < 10 javavm wherein eclipse runs: - peak handles: 515 - user handles: ~ 270 - GDI handles: ~ 370 This seems not much at all in comparison with the description of similar cases. When the error occures, there is no significant increase in handles. Is there another tooling that I can use to find out more? Here are some more details to reproduce the error: 1. open at least 3 files in java-editor 2. split the editor horizontally in 3 parts 3. use resize buttons 4-10 times 4. try to edit one of the open files Once this error had occured, it only goes away with a reboot. I hope that helps. I'm using a 64-bit 1.7.0_01-b08 on Windows 7 and do not have this problem. Dean or Oleg, can you reproduce this problem on Windows 7? I can't reproduce it on Windows 7 assuming "split editors" means having multiple editors visible like in the attachement. Florian, is that what you meant by "split editor"? May be there are some specific steps that we need to duplicate this? Created attachment 207324 [details]
Something like this?
(In reply to comment #6) > Created attachment 207324 [details] > Something like this? Yes, exactly. I hope I can test today (in approx. 10h) on another pc. If someone can reproduce it, then please provide the steps and reopen the bug. I am seeing this problem. Happens with both 32-bit and 64-bit Juno C/C++ version At first thought it might be limited to my workspace, so I tried creating a new one and I still see it. Followed these steps: Create new workspace (named it testing) Create new project: General->Project (named it test) Create new file: (named it test.txt) Select Window->New Editor Drag the new copy of test.txt so that you have to editors one above the other Try to work (type/scroll/whatever) in the recently dragged window. Error happens almost immediately with this output: eclipse.buildId=M20130204-1200 java.version=1.7.0_21 java.vendor=Oracle Corporation BootLoader constants: OS=win32, ARCH=x86, WS=win32, NL=en_US

eclipse4.3 RC3 error log
Still happens with Eclipse 4.3 RC3. See attachment It appears that the problem is related to Actual Multiple Monitors. So far, I haven't had it happen with that disabled. I file a bug on their site. . *** This bug has been marked as a duplicate of bug 402983 *** |
