space left on device, chances are you need to increase the number of semaphores in your system. But first of all, what are semaphores? A semaphore is an inter-process communication (IPC) facility used in UNIX. In computer science speak, it is a method of controlling access by several processes to a common resource in a parallel programming environment. There are two kinds of semaphores: binary and counting. A binary semaphore is a simple "true or false" flag that controls exclusive access to a resource. A counting semaphore is used to control concurrent access. The counting semaphore as implemented by IPC https://scn.sap.com/thread/3761512 is what concerns us in this article. IPC semaphores are themselves a finite resource; that is, there's only a certain number at any given time. If a process requires access to a resource then it obtains a semaphore and the number of available semaphores is decremented. Once the process has finished with the resource it returns the semaphore and the available semaphore count is incremented. The error above is http://unixhowto.filodownunder.com/?p=13 generated when the number of available semaphores reaches zero. To find out the current status of IPC facilities; e.g. number of semaphores in use, run this commnand: root@non_g_zone:/# ipcs -s IPC status from as of Tue Mar 9 14:02:49 EST 2010 T ID KEY MODE OWNER GROUP Semaphores: s 2072 0x68697a82 --ra-ra-ra- oneusr onegrp s 2069 0x26b0 --ra-ra-ra- twousr twogrp s 2068 0x26a6 --ra-ra-ra- twousr twogrp s 2067 0x2693 --ra-ra-ra- twousr twogrp s 2048 0x1f63 --ra-ra-ra- twousr twogrp s 16777412 0x1f26 --ra-ra-ra- twousr twogrp s 16777391 0x1f12 --ra-ra-ra- twousr twogrp s 16777388 0x1ebb --ra-ra-ra- twousr twogrp s 2047 0x1e7d --ra-ra-ra- twousr twogrp : {snip} : s 2043 0x1d9a --ra-ra-ra- twousr twogrp root@non_g_zone:/# This information applies to the default project.
