Dear All, I have a Intel desktop machine having P4 processor and 512MB RAM. It has a custom 2.6.25 (custom because config has been changed to de-select/select unnecessary/required things before compilation) running over SLES10 distro. I have noticed that this machine tends to hang after running un-interrupted for a certain number of days. There is no fixed pattern that happens (no fixed number of days), and hangs might occur as frequent as 2-3 days and as delayed as 7 days. I have noticed this happening for no apparent reason. This machine is being used as a ssh box containing a repository of kernel sources - thats it. There is no configured web-server or background application running on this. Problem: 1. The hangs is such that there is nothing on the display and hence I cannot see what state the machine is (not that I am expecting that would help in such case). 2. There is nothing unsual in /var/log/messages, /var/log/warn, /var/log/mcelog ... and many other log files. 3. There is no crash dump either, even when I have configured kexec/kdump on this. It work, becuase I tested it by triggering using sysrq. 4. There are no kernel messages about any failed device or similar things in past logs (once I have rebooted). Output of /var/log/messages from one of the most recent stall is: ---8<---- Jun 9 04:25:35 DogMatix syslog-ng[3516]: STATS: dropped 0 Jun 9 05:25:36 DogMatix syslog-ng[3516]: STATS: dropped 0 Jun 9 06:25:36 DogMatix syslog-ng[3516]: STATS: dropped 0 Jun 9 07:25:36 DogMatix syslog-ng[3516]: STATS: dropped 0 Jun 9 08:25:36 DogMatix syslog-ng[3516]: STATS: dropped 0 Jun 9 09:25:36 DogMatix syslog-ng[3516]: STATS: dropped 0 Jun 9 12:44:12 DogMatix syslog-ng[2732]: syslog-ng version 1.6.8 starting ----8<---- Notice that syslog is printing something each hour, and then there is stall after 09:25. Last line is bootup message after hard-booting the machine. Dogmatix is the name of the machine. Question: What should be done in such situations? What can be a reliable method to know the real reason behing such stalls? Any ideas/hints/suggestions are most welcome. I would like to solve this mystery rather than live with it. -- Shreyansh -- To unsubscribe from this list: send an email with "unsubscribe kernelnewbies" to ecartis@xxxxxxxxxxxx Please read the FAQ at http://kernelnewbies.org/FAQ
