Right now the server has all of the latest and greatest patches from Red Hat. We are still seeing crashes about once a day.
I am also observing a significant memory leak on this box, though I can't figure out if its Tomcat, java, the code or something else - once the memory gets low enough tomcat crashes. I am planning on making the following config changes to hopefully remedy this problem: -Xms512m -Xmx512m -XX:NewSize=256m -XX:MaxNewSize=512m -Xincgc This machine has about 2gb of memory and the app running on it is fairly database intensive. Can someone tell me if these settings make sense? Thanks again. --- "Shapira, Yoav" <[EMAIL PROTECTED]> wrote: > > Howdy, > > >Signal 11 is a segmentation error (I think), which > would be caused by > >attempting to access an invalid memory address. > This in turn might be > >caused by attempting (in native code) to construct > an instance of a > Java > >class that the class loader can't find, something > like: > > This is unnecessarily restrictive, although a > possible explanation, as > signal 11 is not just segmentation fault.
