Hi,

I found ‘gem up’ command hangs on one of the machines.

$ sudo gem up  
Updating installed gems…

# (hangs here…)

ERROR: While executing gem … (Errno::ETIMEDOUT)  
Connection timed out - connect(2)

Strange, so I tried with strace(1):

$ sudo strace gem up  
connect(3, {sa\_family=AF\_INET, sin\_port=htons(80),  
sin\_addr=inet\_addr(“66.92.150.242”)}, 16) = -1 EINPROGRESS (Operation  
now in progress)  
select(4, NULL, [3], [3], NULL) = 1 (out [3]) # hangs here…  
connect(3, {sa\_family=AF\_INET, sin\_port=htons(80),  
sin\_addr=inet\_addr(“66.92.150.242”)}, 16) = -1 ETIMEDOUT (Connection  
timed out)  
fcntl64(3, F\_SETFL, O\_RDWR) = 0  
close(3) = 0  
rt\_sigprocmask(SIG\_SETMASK, [], NULL, 8) = 0  
write(2, "ERROR: While executing gem … "…, 88ERROR: While  
executing gem … (Errno::ETIMEDOUT)  
Connection timed out - connect(2)) = 88  
write(2, “\n”, 1  
) = 1  
rt\_sigprocmask(SIG\_SETMASK, [], NULL, 8) = 0  
rt\_sigaction(SIGINT, {SIG\_DFL}, {0x80b04dc, [],  
SA\_RESTORER|SA\_RESTART, 0x55f8c8}, 8) = 0  
munmap(0xb7ec3000, 4096) = 0  
exit\_group(1) = ?

What’s this 66.92.150.242?  
It seems this host has no internet connection.  
select(2)'s hanging on seems another problem.

Any thoughts?

This problem was caused by nscd(name server cache daemon).  
However gem should be able to handle such network error.
