Running the 2line script below crashes most of our intel based (with e1000
nics) servers:
#!/usr/bin/python
import urllib
urllib.urlretrieve("http://www.somesite.org/afile.tar.gz";, "/tmp/file.tgz")
The download start but then ssh connection is completely lost and system is not
responding anymore on network conections
the last messages seen via dtrace:
recv(0x4, 0x8192D74, 0x1) = 1 0
recv(0x4, 0x8192D94, 0x1) = 1 0
recv(0x4, 0x8192DB4, 0x1) = 1 0
recv(0x4, 0x8192DD4, 0x1) = 1 0
recv(0x4, 0x8192DF4, 0x1) = 1 0
recv(0x4, 0x8192E14, 0x1) = 1 0
recv(0x4, 0x8192E34, 0x1) = 1 0
recv(0x4, 0x8192E54, 0x1) = 1 0
On the console we see the script is consuming 100 % of 1 cpu core, when we do
dladm show-dev via the console, the system freezes completely, So it looks like
a device is gone ... the system is completely locked and we have to restart.
It seems to happen on different servers, all running build 93+ and all intel
based, testing on same hardware with build 91 does not crash the system. we
tested bfu to build 95 but without success, system still crashed with the above
2 lines script
Problem can not be reproduced on AMD boards (with broadcom nics)
Can someone with x86 intel system and build 93 confirm the above script crashes
him or her system as well?
Does anyone knows a cause of this problem?
