I left my laptop running F8 ( 2.6.24.4-64.fc8 x86_64 kernel) on with Firefox, with multiple sites opened, Evolution and maybe some small applications like a xterm. When I came back after 4-5 hours, I found that the system was frozen and I could not access it either through the GUI where I was working or through any of the consoles. None of the keys or key combinations were working. I could ping it from the other system but could not access it through SSH also and was forced to switch off the power and reboot it. In the both the instances, after rebooting the system I examined the system monitoring graphs I generate using a program called systemgraph and discovered that over a 3 hour period: 1. The physical memory used increased to 2414 MB out of a total of 2508 MB (as shown by free command). I have 2.5 GB of RAM installed. 2. The swap used had increased to 1999.32 MB against the available swap space of 2047MB. 3. The CPU context switches had increased to a maximum of about 54,000 per second as compared to the average of about 4500-5000. Similarly the pages in and out had increased to about 1700 and 2300 per second against the average values between 20-30 per second. 4. The disk I/O also showed a 100 times increase and the load average also increased manifold 5. However, there was no significant change in number of processes or number of open files. I tried to find out if there was any data regarding resource utilization by various processes during this period but could not find any and therefore I was unable to pinpoint the cause and was suspecting some kernel bug. But looking at your mail, I think it could be firefox which is causing the problem. However, no idea why. Maybe someone can explain this. -- Manish -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list
