Slow site caused by poll() event – out of my depth!


I’ve noticed my site running slowly recently and asked my webhost to have a look for any processes running in the background that may be slowing it down. They said it is likely to be related to what the index.php file is doing. After checking exactly what calls and process the index page was doing they identified that in the following two processes, one is taking a rather long time 4.7 seconds.

09:28:18.007859 recvfrom(5, 0x5d3ef88, 5, 0, 0, 0) = -1 EAGAIN (Resource temporarily unavailable) <0.000009>

09:28:18.007895 poll([{fd=5, events=POLLIN|POLLPRI}], 1, 5000) = 1 ([{fd=5, revents=POLLIN}]) <4.749779>

09:28:22.757759 recvfrom(5, “”, 5, 0, NULL, NULL) = 0 <0.000031>

I do not know where to begin in understanding this or fixing it.

Any help and guidance would be greatly appreciated
