I can't be sure, which job actually freezes the system, a good runner up is updatedb, [...] Sounds like your system has either too little memory for your workload or has a problem with (heavy) IO. By freezing; do you mean that the system feels slow, or does it hang completely? In either case, you might want to check dmesg for errors. If everything is working but just slow, check your memory usage and/or try to reschedule both tasks (updatedb and mandb) to a more convenient time. I think the cgroups can also help here, but that's a bit of longshot for me. Mvg, Guus Snijders
