Hi!
I have a problem caused by inaccurate timeouts in epoll_wait(2).
Here are some parts of strace -tt output:
22578 09:33:46.959791 epoll_wait(5, <unfinished ...>
22578 09:33:50.010794 <... epoll_wait resumed> [], 128, 1498) = 0
...
22034 09:35:07.686896 epoll_wait(5, <unfinished ...>
22034 09:35:09.482526 <... epoll_wait resumed> [{EPOLLIN,
{u32=151458248, u64=151458248}}], 128, 362) = 1
...
22036 09:35:41.433241 epoll_wait(5, <unfinished ...>
22036 09:35:43.176881 <... epoll_wait resumed> [], 128, 97) = 0
In each example epoll_wait is blocked for too longer then asked in timeout.
Is it normal?
Please CC me.
