[nodejs] open() syscall errors and friends
I am attempting to debug random slowness in an application and before I
google the web too much, I thought I'd ask here:
% time seconds usecs/call callserrors syscall

The connect() errors stem from redis, but from what I gather a EINPROGRESS
is not a bad thing...
*[pid 8039] connect(53, {sa_family=AF_INET, sin_port=htons(6379),
sin_addr=inet_addr("10.24.24.122")}, 16) = -1 EINPROGRESS (Operation now in
progress)
*
These open() errors confuse me:
*[pid 8032] open("/sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_max_freq",
O_RDONLY) = -1 ENOENT (No such file or directory)*
*[pid 8032] open("/sys/devices/system/cpu/cpu1/cpufreq/cpuinfo_max_freq",
O_RDONLY) = -1 ENOENT (No such file or directory)*
*[pid 8032] open("/sys/devices/system/cpu/cpu2/cpufreq/cpuinfo_max_freq",
O_RDONLY) = -1 ENOENT (No such file or directory)*
*[pid 8032] open("/sys/devices/system/cpu/cpu3/cpufreq/cpuinfo_max_freq",
O_RDONLY) = -1 ENOENT (No such file or directory)*
I was not able to capture the epoll_ctl errors...
Any thoughts?
