I have been collecting data for Anthony for a month on this problem, but it changed twice after Git updates. There were 2 different leaks and it seems both may be fixed. I am posting for Anthony and anyone with FreeSWITCH on OS X who may want to update: LEAK 1 The Big Leak - noted in jira 2008 FreeSWITCH allocated 2.3 to 2.3 meg per hour with no calls in or out. This required daily restarts. This leak fixed after Nov 22 Git. LEAK 2 After November 22 2010 Git - I updated before I sent the observations since developers want the latest Git tested. Good thing I did, the previous big leak disappeared! However, each in or out call added 400-500k to FreeSWITCH. It was never released in any 24 hour period. LEAK 3? After December 7 Git - Only a small amount (150-200k) is added per call. But.... I also tested in Linux at the same Git level and it did the same thing so this may be normal. I updated the OS X Wiki with the recommended Git version. Mario G
