I am seeing this same problem on my debian production server. top shows the correct number of processes, but each mongrel instance and ruby running backgroundrb all are ballooning to 15% memory consumption within a day or two. The application is http:// myfreecopyright.com
It may be in the code, but how do I troubleshoot this? Cheers -Matt On Jan 17, 2007, at 2:34 PM, Ezra Zygmuntowicz wrote: > > Some linux distros have weird reporting of processes.
