What I found out is that unlike Qt 3 (which apparently has a file-descriptor limit of 1024) Qt 4 will go as high as 6144 open FDs, and if your file-descriptor limit (set in /etc/security/limits.conf on Ubuntu distros) is lower than that, Qt4 Opera will spin at 100% CPU and act "funny" when it hits that lower limit. I set mine to 8K hard, 6K soft for user "kenny" and all was well. (But I ended up going back to Qt3 over minor issues like favicons disappearing). -Kenny -- Kenneth R.
