Why don't you clone your machine, or use Vmware or something, and do an test before you do it with your production-machine? Asking this sort of question is, well, rather meaningless IMO. Your setup is unique considering what tweaks you might've done to it. YMMV as they say. What works for me, doesn't necessarily work for you, or vice versa. Testing before use in sharp situations is always a good idea, although I've been pampered and spoiled by CentOS's stability on inplace-upgrades, like this last one. 8-} -----Original Message----- From: centos-bounces at centos.org [mailto:centos-bounces at centos.org] On Behalf Of fabian dacunha Sent: Thursday, June 26, 2008 8:46 PM To: centos at centos.org Subject: [CentOS] is centos update safe Dear All, I am curently running a CENTOS server with the following setup CentOS release 5 (Final) Kernel 2.6.18-8.1.8.el5xen on an i686 bind-9.3.3-10.el5 sendmail-8.13.8-2.el5 apache httpd-2.2.3-11.el5_1.centos.3 MailScanner ver 4.66.5 ClamAV 0.92 SpamAssassin version 3.2.4 SquirrelMail ver 1.4.13 Now all this have been workin perfectly fine for a long time. now if i do a yum upgrade i see the following Install 29 Package(s) Update 415 Package(s) Remove 0 Package(s) and the total download size is abt 579 M i jus wanted to know if i could SAFELY apply the updates since its a live server running our companys primary DNS and mail server has any body done this b4 i know the Centos will be upgraded to 5.2 but has anybody applied these updates and its been workin fine after reboot and also about the various software currently running on the server apprecite your help and asvise regards Fabian -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean. _______________________________________________ CentOS mailing list CentOS at centos.org http://lists.centos.org/mailman/listinfo/centos -------------- next part -------------- A non-text attachment was scrubbed...

Just quietly dies with nothing in the logs. Several other upgraded systems (all i386) seem to be fine. Still searching for any other reports of problems. Phil
