It turns out that: auditctl -a entry,always -S socketcall is what triggers the hang. I remember auditing socket calls when working on ausearch interpretation code. So I booted into old kernels. .61 runs, but starts heavy disk activity. .62 runs, but reports backlog overflow to console .63 hangs. The changelog for .63 says: - Wait for backlog to drain where possible So, my guess is that there is something in the draining of the backlog that causes this problem. The audit logs from .62 shows that recvfrom() for auditd is being audited over and over. I also wonder if this is related to the problem Debbie & Denise were reporting? It seems similar - system hung, no visible indicators that it hit the backlog draining. -Steve
