Ioexception Cannot Allocate Memory


At a bare minimum you should give us the exception stack trace and a few of the lines of code where the exception occurs. Had the same issue with OpenJDK in my VPS (when I had it) and when I switched to Sun Java 6, everything was fixed. Better approach is that you experiment your case & give a good swap space & give a better ratio of physical memory used & set value to 2 rather than 1 specifies explicit collection once per hour instead of the default rate of once per minute. have a peek at these guys

Why was this unhelpful? You signed out in another tab or window.

Since fork() duplicates the process and its memory, if your JVM process does not really need as much memory as is allocated via -Xmx, the memory allocation to git will work.

It is also implemented in java_posix_spawn. your overcommit solution, it permits overcommitting of system memory, possibly allowing processes to allocate (but not use) more memory than is actually available. So I guess that the fork() duplicates the Java process memory as discussed in the comments below. Do free -m to check how much memory is available.

Plus that exec spawns new processes with the same RAM usage as the origin process –Karussell Jan 25 at 15:01 add a comment| up vote 5 down vote If you look root is allowed to allocate slighly more memory in this mode. git) a system call is made to fork() which effectively duplicates the current process and all its memory (Linux and others optimize this with copy-on-write so the memory isn't actually copied
