[Qt-creator] Polling and running in circles

[Adam Majer]

This is an strace of qt creator in Debian. I don't know what it is
trying to do, but it is using about 2% of CPU doing it.

/etc/localtime, as far as I know, is a copy of the timezone data. It
should not change often, so why continued requests on it?

But more importantly, the other read() requests and poll is looping
rather fast. Any ideas where this is coming from?


poll([{fd=3, events=POLLIN}, {fd=11, events=POLLIN|POLLPRI}, {fd=13,
events=POLLIN|POLLPRI}, {fd=14, events=POLLIN|POLLPRI}, {fd=15,
events=POLLIN|POLLPRI}, {fd=16, events=POLLIN}, {fd=17, events=POLLIN},
{fd=7, events=POLLIN}, {fd=19, events=POLLIN}], 9, 0) = 0 (Timeout)

read(7, 0x2538624, 4096)                = -1 EAGAIN (Resource
temporarily unavailable)

stat("/etc/localtime", {st_mode=S_IFREG|0644, st_size=2865, ...}) = 0

read(7, 0x2538624, 4096)                = -1 EAGAIN (Resource
temporarily unavailable)

read(16, 0x25e7374, 4096)               = -1 EAGAIN (Resource
temporarily unavailable)
