MATLAB ERROR I/O? IT IS A BUG?
显示 更早的评论
Why matlab gives me these errors only occasionally and only after a few minutes of processing? I believe that 92160800 is a generated file while matlab writing xls file.
ERROR:

I find "xlsread" as tag. Does the problem occur during you run xlsread? This would be important. But then you write "92160800 is a generated file while matlab writing xls" - so do you write an XLS-file? Why do you assume, that this file is generated, although the error message tells, that this file does not exist?
Please post the commands, which causes this error and tell us mot about the 92160800-file.

Occasionally I get java errors like that. They've not been reproducible, and fortunately they're rare. (Sometimes it seems like they're more common if I'm sharing my desktop with someone over the LAN.) Restarting MATLAB seems to get rid of them.

I don't use databases with MATLAB. If you have code that will reliably/repeatably cause the java crashes, then send it to the Mathworks and have them research it.
If each 100 writing fails, what about writing 99 files only and hide the 100th writing in a TRY/CATCH?
Or open the Java.exe in a text editor and search for "100". Set it to "10000" and try it again, when this number is sufficient.
;-)
Sorry, I hate hate hate this instable Java stuff. How can I install a large project with several 100'000 lines of Matlab code, which is debugged exhaustively with a sophisticated quality control, unit-tests, automatic integration tests and all bells and whistles for a serious application like clinical decision making, when Matlab crashes due to forgotton syncs between java threads?! It is like driving an expensive and comfortable car, when one of the wheels is exploding every 100 km.
