Product Version = NetBeans IDE Dev (Build nbms-and-javadoc-179-on-20150730) Operating System = Windows 7 version 6.1 running on amd64 Java; VM; Vendor = 1.8.0_45 Runtime = Java HotSpot(TM) 64-Bit Server VM 25.45-b02 I've been having this issue since the early NB 6.0 now. There seems to be some Memory leak which causes Netbeans to shutdown when a project is being tested. This testing is done as follows: 1) PHP unit + custom bat file 2) bat file executes external test framework 3) the output tab in NB is filled with the results But occassionally, every day 4 or 5 times, I guess 1 every 50 times I execute this Test All (or test file, doesnt matter), NB crashes. Very occassionally, I do even have BSOD, failing in Netbeans dll. Something thats points to memory leakage is that Chrome sometimes also get killed, but not every time. If you ask me where to put the finger, I would say it has something to do with the I/O in the Netbeans Output tab/window. I have now allocated 12GB of RAM but is still occurs.

> Something thats points to memory leakage Memory leaks in NetBeans usually cause OutOfMemoryErrors, not BSOD. NetBeans IDE probably is not causing this OS crash. Output Window is using a file-mapped memory, but via standard Java API. If access to this memory caused this problem, it would be an OS issue. After some searching, it seems that there can be some hardware (or driver) problem: Some similar cases: - http://answers.microsoft.com/en-us/windows/forum/windows_7-performance/defaultbucketid-vistadriverfault/1bc09338-463f-42b6-82c0-43229a4f6c73 (invalid RAM memory) - http://forum.corsair.com/v3/showthread.php?t=98617 (problem with SSD driver) Please try running some diagnostic tools (memory check) to ensure you computer is healthy first. Thank you.
hi Jaroslav Havlin , thanks for your detailed answer. In fact, I am making use of a RAM disk for all of my temporary files, including Netbeans. Do you think the problem could be in there?

Otherwise, it should work normally, I think. I'm sorry, I'm not much experienced in this area - bugs that involve OS and possibly hardware.
it does seem to be faulty SSD. Firmware fixes for crucials M4 still dont seem to do the trick. After switching, I havent had this issue anymore. thnx for pointing me in the right direction Jaroslav Havlin!
You are welcome. I'm glad it helped :-)
Unfortunately, my issue also exists when using other SSD drives. Is there a way to get relevant data to post here?
I'm sorry, I have no other idea. I don't know what could be wrong.
Please see bug 256160, it may be related to the problem you reported.
