and data not immediately required in memory. Any data written during this condition is probably lost. Action Reinstall or reconfigure the system to have more swap space. A general rule is that swap space should be two to three times as large fork failed not enough space datastage as physical memory. Alternatively, use mkfile(1M) and swap(1M) to add more swap area. This example shows how to add 16 Mbytes of virtual memory in the /usr/swap file (any file system with enough free space would work): # mkfile 16m /usr/swap # swap -a /usr/swap To make this reconfiguration automatic at boot time, add the following line to the /etc/vfstab file: /usr/swap - - swap - no - Technical Notes When calling the fork(2), exec(2), sbrk(2), or malloc(3C) routine, a program asked for more memory than the system could supply. This is not a temporary condition; swap space is a system parameter. The symbolic name for this error is ENOMEM, errno=12.

space when Java tried to fork a process. The problem is inherent with the way Java allocates memory when executing processes.When Java executes a process, it must fork() then exec(). Forking creates a child process by duplicating the current process. By duplicating the current process, the new child process https://docs.oracle.com/cd/E19455-01/806-1075/msgs-1831/index.html will request approximately the same amount of memory as its parent process, essentially doubling the memory required. However, this does not mean all the memory allocated will be used, asexec() is immediately called to execute the different code within the child process, freeing up this memory. As an example, when Stash tries to locate git, the Stash JVM process must https://confluence.atlassian.com/stashkb/forking-jvm-error-12-cannot-allocate-memory-or-error-12-not-enough-space-302809889.html be forked, approximately doubling the memory required by Stash. Note that this issue ismade worse by hostingmultiple webapps in the same Tomcat container as Stash (which is not supported),because more memory is used by the Java process. Please seeForking JVM for a more detailed explanation. Resolution If you are hosting multiple products in the same Tomcat container as Stash, move Stash to its own Tomcat container. For Linux, this can be resolved by enabling over-committing memory (see option 3 ofForking JVM). For Solaris, we recommend increasing your swap space. How much swap space do you need? This will also depend on the other applications running on the same machine.We recommend allocating at least swap equal to 4 x JVM_MAXIMUM_MEMORY, or 2 x PHYSICAL RAM, whichever is larger. The JVM_MAXIMUM_MEMORYis set in your

suffers with low SWAP space. Assume you are having 4GB of swap memory and want it to increase to 20GB. To do that, please follow the steps below SOLUTION: Login as root user To check the current SWAP size # swap –lh The above command will display the current swap size To delete the current SWAP size # swap -d /dev/zvol/dsk/rpool/swap To create the SWAP memory # zfs set volsize=20G rpool/swap To activate the new SWAP memory swap -a /dev/zvol/dsk/rpool/swap To check the current SWAP size # swap –lh You will get the output as displayed in above screenshot Posted in Solaris and tagged fork: Not enough space, solaris, solaris 11, swap, zfs on September 18, 2013 by Prabu R.
