I have this same problem with lucid when using an encrypted swap partition on a 64 bit system.
If a process allocates most of the RAM, the system becomes unresponsive and if within X I have no other option but to force a power cycle. ctrl+alt+sysrq+f (to invoke the oom killer) doesn't seem to do its job, although the system is not completely frozen, since sysrq still display the help messages (ctrl+alt+sysrq+h) and I see some disk activity. Trying with a regular swap partition (not encrypted) works fine, so I assume there's some problem with the kcryptd from the linux kernel. -- System freeze on high memory usage https://bugs.launchpad.net/bugs/159356 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
