When I go to load the cso through the load file option, I get the following error dialog; "IO Error: Map failed" Also here's the command line output in case it helps; http://pastebin.com/RsM0YnfN I should mention I've tried it both as a CSO and also decompressed it to an iso, still doesn't work. I also had to uninstall JRE 7 and install JRE6 instead to get the emulator to run at all, could that be relevant? Any help would be greatly appreciated "I think that the problem with this video is it is highly derivative of many popular bands within the genre. Although when viewed on its own merits, it does have a deeper groove. However what i
failed and java.lang.OutOfMemoryError: Map failed While working with memory mapped file, you may get java.io.IOException: Map failed error, which is mainly caused by Caused by: java.lang.OutOfMemoryError: Map failed error as shown below. This error usually comes while mapping a big file in memory e.g. trying to map a file greater than 1 or 2GB java.io.IOException: Map failed at sun.nio.ch.FileChannelImpl.map(FileChannelImpl.java:888) Caused by: java.lang.OutOfMemoryError: Map failed at sun.nio.ch.FileChannelImpl.map0(Native Method) at sun.nio.ch.FileChannelImpl.map(FileChannelImpl.java:885) ... 6 more How to Solve java.io.IOException: Map failed Depending upon which operating system you are working, e.g. Windows or UNIX, you can try different things to solve this error. http://www.epforums.org/showthread.php?80654-JPCSP-I-O-error One of the quick way to solve this by reducing size, which you want to map into memory. For example if you are trying to map 1GB into memory, you may want to only map 512MB or lower, if your code uses region based approach, this may work file. Alternatively you can also use -d64 and -XX:MaxDirectMemorySize JVM option to enable large direct buffers : http://javarevisited.blogspot.com/2014/11/javaioioexception-map-failed-javalangoutofmemoryerror.html -d64 This JVM flag instruct virtual machine to run on 64-bit mode. Since 64-bit installation on Solaris and may be on other UNIX systems comes with 32-bit JVM as well, which may be efficient for small programs, due to small size of OOPS pointer as discusses on why use -XX:UseCompressedOOPS flag in 64-bit JVM. By providing this option to your JVM you make sure that it's running on 64-bit mode, allowing it to map more memory. -XX:MaxDirectMemorySize This option is not on official list of JVM flags but still a good option to try. It allows you configure memory used by direct buffers. One more option, you can try is -XX:+UseLargePages. For example, if your program is using 6GB of memory mapped file, you may want to pass java -d64 -XX:MaxDirectMemorySize=6g -XX:+UseLargePages BigApp That's all on how to solvejava.io.IOException: Map failed and java.lang.OutOfMemoryError: Map failed. You can use any of these options or combination of them to see what works for you. Make sure you use 64-bit JVM if you are mapping large files in memory. Remember though both error are different, one is IOException and other is OutOfMemoryError, cause is mor

Will list out some of the common causes of an 'ORA-01115: IO error reading block from file (block # )' error over here. Typically, when Oracle failed to read io error a data block from an open data file, it throws an ORA-01115 error. Before you suspect any database issue, it is advised to have a close look at the error message stack presented before and after the ORA-01115 error in the database alert.log file. As there could be a different reason for this error when comparing the same error over io error map the net or previous occurrence, it is pretty important that you isolate the issue looking at the other error messages represented along with this error. One of the following would be the most common reasons for the error: the datafile in the context is OFFLINE database might have lost communication with the underlying ASM instance caused by any hardware problems physical data block corruption at the storage level a Oracle BUG We have encountered similar issue in one of our RAC databases due to communication loss with the underlying ASM instance.
