The current AS2.1 supported kernel is 2.4.9-e.72. A number of vm-related bugs have been fixed since -e.35. Is this problem present in 2.4.9-e.72? Hi Daniel - I don't have enough info to go on and have not heard back from you. I'm going to close this bug. If you'd like to persue this further, please re-open this bug, and open a case with redhat support at enterprise.redhat.com. Thanks. What kind of info do you want to know? When I begin a backup, machine turns very slow, and making a top, CPU usage is 100%. Sometimes services, applications or all machine hungs. Thanks in advance. Daniel. I have two identical machines, and both have same problem. Can you reproduce this problem on 2.4.9-e.72? If so, can you provide sysrq-m and sysrq-t output? Then, Is the problem fixed in 2.4.9-e.72? Or is this a test? Hi Daniel - e.35custom is a _very_ old kernel, and not one that we can support at this point. As I said in comment 1, there have been a number of vm patches, several specifically for kswapd since e.35. Please give e.72 a try. If the problem occurs there, please collect the sysrq info and post it here. Thank you for submitting this issue for consideration in Red Hat Enterprise Linux. The release for which you requested us to review is now End of Life. Please See https://access.redhat.com/support/policy/updates/errata/ If you would like Red Hat to re-consider your feature request for an active release, please re-open the request via appropriate support channels and provide additional supporting details about the importance of this issue. |
