cron stops silently
Hi, Since updating our server to 5.4-STABLE, I've noticed a very strange problem with cron. Sometimes it just decides to stop, for no apparent reason. It stops at different times, it doesn't seem to be affected by any particular cronjob. There are no messages about this in any logfile, it just stops running and I have to start it manually. Obviously this is a major PITA. Can anyone help me to debug this problem further? I really don't know where to look. Searches of all freebsd mailing lists have turned up with nothing.

updating from 5.2.1 to RELENG_5
As per subject, I need to do this urgently, but with minimum downtime. Will it be ok just to cvsup, rebuild kernel and world, mergemaster, (etc) like any normal update? Or do I have to do a reinstall? Any help appreciated.

You should be able to use libmap.conf to work around it until you recompile all your ports. Yes, it referrs to compat4x libraries. Not an issue for me, since I'm upgrading from 5.2.1 to RELENG_5. Regarding libmap, yes I have used it before. Basically, I'm looking for advice from people who have done this particular upgrade. Its an upgrade that should be straightforward. I was only wondering if there were any extra little gotchas that I should consider. Thanks for all the replies so far.

performance under heavy load
Hi, I'd just like to give some credit to the freebsd developers for a job well done. A user on our system ( freebsd 5.2.1 smp ) managed with a runaway script to start up 500 intensive processes, raising the load average to about 200. We managed to remotely, over ssh get a somewhat responsive session and kill the offending processes. Yes, I know we shouldn't have let it happen in the first place, by putting in proper user limits and all that, but it was amazing that the machine still worked. We thought we'd have to reboot. Even with a load of nearly 200, the machine was still able to serve web pages :) Once the load came down past 60, the system feltl fully responsive again. On linux, we would have had to reboot in this situation. On a highly linux machine, you lose all control of the machine past a load of about 6 - 10. This just further vindicates my decision to use freebsd for this service. ( Its a shell server with about 100 active users, apache, nfs, mysql, ldap ). Just wanted to share a success story :) Regards, Philip Brennan ___ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to [EMAIL PROTECTED]
Re: performance under heavy load
True, on that linux machine its more io load than anything else. But anyway, the problem was caused by fortune -l going into an infinite loop, and a script running this every 5 minutes.

I had cases of LA climbing over 150 on linux machine - it was extremely slow but I could get it back to life w/o need for reboot.

Thats impressive, do you know what spec that machine is?
