Running firefox with strace shows it hitting these two poll lines, where it just sits doing nothing for a long time? Actually, pauses after displaying up to the NULL,8 then it goes on until it hits the second one.
First on has always been fd=10, but have seen fd=14 or fd=13 for second??
ppoll([{fd=10, events=POLLIN}], 1, {tv_sec=119, tv_nsec=999420000}, NULL, 8) = 1 ([{fd=10, revents=POLLIN}], left {tv_sec=46, tv_nsec=773625894}) ppoll([{fd=14, events=POLLIN}], 1, {tv_sec=119, tv_nsec=999274000}, NULL, 8) = 1 ([{fd=14, revents=POLLIN}], left {tv_sec=113, tv_nsec=850834948})
$ time firefox
real 2m43.247s user 0m3.097s sys 0m0.795s
As soon as I shows the firefox windows clicked on X to close to get approximate time.
Firefox had been updated earlier, and didn't seem to do this, but just updated to the latest kernel 5.11.17-200.fc33.x86_64 and rebooted, and the noticed it?
looked at lines before this after directing strace to a file, but didn't see anything obvious?
Thanks.
