From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux 2.2.12-20 i686; en-US; m18) Gecko/20001108 BuildID: 2000110808 While mozilla in the 'request sent, waiting for reply' state loading a page, it takes 100% cpu. Reproducible: Always Steps to Reproduce: 1.Connect to for instance a telnet port ( http://server:23 ) 2.Notice CPU usage going to 100% Also note the spinner not spinning. Actual Results: Mozilla used all CPU time Expected Results: Wait, and not use any CPU time and spin the spinner Asa noticed this on his Win32 machine too.
I see this also on WIN2k, build 2000110804. The spinner also isn´t spinning while the 4.xx profile is converted. The spinner must be broken in the last 2 days.

Priority: P3 → P2
I noticed this on Win95 20001108 builds when trying to vist some sites that were bogged down with election coverage. The site was slow and justt making me wait. Durring that time my CPU usage was sky high and everything was slow.
I also observe this 100% utilization with 11-08-00-Mtrunk build on NT4-SP6a. I eliminated the possibility that it's related to the DNS call by loading content from a local server (with a straight IP address). Finally, isn't the mouse pointer supposed to switch to the pointer+hourglass when anything is still processing? I have trouble telling if a page is done downloading because the mouse pointer doesn't change and the "Document: Done" message appears prematurely.
This bug seem to be fixed after mkaply backed out his fix for bug 55997. Can someone confirm this with a daily build ?
Linux build 2000111498 - I connected to a telnet server as suggested by the reporter. Top reports mozilla using 4.3% of CPU and the animated mozilla icon is going (I assume that is what is meant by spinner).
It´s not the animated mozilla icon. Spinner means the blue animated lines at the left buttom. (only classic skin)
Spinner is moving just fine as well.
I now mark this fixed. After Mkaply backed out his fix, this bug seems to be fixed. (I told mkaply about this bug)
