All,

For some time i am experiencing the high cpu rate on Firefox (2.0.0.14, Fedora 8) with some sites (sites with flash are always high on cpu and crash sometimes). I have done the following to find out what is going on when firefox is high on cpu.

#  ps -p 27727 -mlfFL

As per the above output the thread with LWP 15572 has the following from pstack output.

Thread 7 (Thread 164613008 (LWP 15572)):
#0  0x00110402 in __kernel_vsyscall ()
#1 0x00be95d5 in pthread_cond_wait@@GLIBC_2.3.2 () from /lib/libpthread.so.0
#2  0x08196ff8 in __cxa_pure_virtual ()
#3  0x08291438 in __cxa_pure_virtual ()
#4  0x0819734d in __cxa_pure_virtual ()
#5  0x00be550b in start_thread () from /lib/libpthread.so.0
#6  0x00b26b2e in clone () from /lib/libc.so.6

It appears that "pthread_cond_wait@@GLIBC_2.3.2 ()" could be the cause for high percentage of CPU but don't know how to go further with this.

Any help would be appreciated.

Thanks

Srikanth
