I recently upgraded to CentOS5, and now I have application that suddenly close. Did not have any problem under 4.x Applications that crash regularly. Claws mail [compiled under CentOS5] VMware 5.5.3 workstation I see nothing in /var/log/messages. In vmware-0.log I have: May 11 00:18:56: vmx| * May 11 00:18:56: vmx| * The UI terminated unexpectedly. May 11 00:18:56: vmx| * If you file a bug or support request about this issue, May 11 00:18:56: vmx| * please include log and core file(s) from the UI if May 11 00:18:56: vmx| * available. May 11 00:18:56: vmx| * May 11 00:18:56: vmx| Unable to continue without a UI. Any suggestion on what's causing the crashes. I have plenty of free disk space 60Gb+ I use NVIDIA 6200 with the NVIDIA driver compiled on this computer Any suggestion of what I should look for to further investigate? -- Thanks http://www.911networks.com When the network has to work
