Hi,

Firefox -----
During certain operations, such establishing a connection but not receiving a
reply I've noticed that estd raises the CPU frequency and puts it up to the max.
Taking a look at top I don't see anything obvious like xulrunner-bin process
using a lot of CPU.

In the mean time I ktrace'd xulrunner-bin and here's the result:

Total CALL lines in the ktrace.out:

[dfbsdx64] ~/@@0x00000002368ec770> kdump -f ktrace.out | grep CALL | wc -l 
 1309637

Thunderbird ----
I haven't been able to establish a relation on why this happens, neither I've
done a ktrace but I will try to do it next time it happens.


[dfbsdx64] ~/@@0x00000002368ec770> kdump -f ktrace.out | grep CALL | grep poll |
wc -l
  315401


I don't know where the problem is yet. Some more information from other users
experiencing the same issue would be helpful, I guess. 

Cheers,
Antonio Huete
