Once again we must teach a newbie about memory usage and the tools they use to check it. If you where looking at memory usage via top, you nee to subtract from the used memory the buffers and cache. Buffers and cache can be freed anytime the system needs memory. It rarely will reduce unless you need that physical memory. Linux, like any other modern OS, will use all the physical memory possible to cache the harddrive. Remember your hardrive access time is measured in milliseconds, and usually in the 5-9 millisecond range. Your memory is going to be measured in nanosecond or less. So realize that Linux is going to try and use as much memory as possible for any file access it thinks you will do often enough to get some speed increases. Think of how many audio files you touched, the config files, any libraries your tools link with, any binaries you have run, and any log files you have looked at. The cool thing is Linux can just discard the cached entries when a application needs real RAM. Don't worry about your RAM usage until you see swap climbing and/or the buffers and cache dropping down to near zero. -- Steven Critchfield <[EMAIL PROTECTED]> _______________________________________________ Asterisk-Users mailing list [EMAIL PROTECTED] http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
