Adobe Reader plugin causes massive CPU usage in SuSE9.1

Hi All, I have seen that the CPU usage on my SuSE9.1 machine skyrockets whenever the pdf plugin is loaded for Mozilla. To reproduce this, just go to any website and load a pdf within Mozilla via the plugin method. Run 'top' or 'xosview' and notice the CPU usage. BTW, this only happens for the plugin - If I save the pdf and invoke from a shell, I don't see the same CPU hogging. Has anyone else seen this? Is there a workaround/fix for this for SuSE9.1? Packages: acroread-5.09-4.2 mozilla-1.7.2-9.1 TIA. Pete

Have found the same symptoms here on 2 different boxes running Gentoo using various 2.6 kernels. Only occurs when reading an on-line PDF with mozilla firefox. KN --

I see the same thing on my 9.1 box. Use plugin, CPU skyrockets. Invoke acrobat reader for pdf files outside of Mozilla/Firefox...no problem. Same versions of acroread and mozilla.

Hi All,

I have seen that the CPU usage on my SuSE9.1 machine skyrockets whenever the pdf plugin is loaded for Mozilla.

Known bug, almost a year old. See: http://bugzilla.suse.de/show_bug.cgi?id=33157 http://bugzilla.mozilla.org/show_bug.cgi?id=198954 Appears to be a Mozilla bug. It is not in Firefox. It is still in Mozilla 1.7.3. HTH, Jeffrey

Pete .

I use 1.7.3 on 9.2beta3 and it is present. As earlier posts have noted, it does not occur on all setup ups. As noted in the bug reports, it occurs on 9.1. The initial bug report is from November of 2003. Jeffrey -- Vote early and often. Apathy only encourages the bums.

Thanks all for the confirmations and for the informative links. I'm going to override the MIME Application handler and go with that for now. Pete
