Unexpected error: httplib.BadStatusLine on create tests

Unexpected error: httplib.BadStatusLine on create tests

[Murillo F. Bernardes]

For a long time I can't run xm-test completely because of that error. After 
this happen xend dies and i get only connection refused.

It use to be always on create tests, but not always in the same test.

Any ideas?

Xend is crashing - bug #411.

What version of Python are you using, and which hardware / kernel are you
using?  I'm trying to get a handle on that crash at the moment.

Ewan.

Yeah. I saw this bug report. 

My xend crashes but I didn't lose network.

RE: Unexpected error: httplib.BadStatusLine on create tests

[Petersson, Mats]

In my experience, httplib.BadStatusLine is a result of xend dying,
rather than the other way around... 

It's possible to (sort of) debug xend by attaching a GDB to the process
running xend - start xend as usual, "ps ax|grep xend", and pick out the
process number for xend, then start gdb and do "attach X" where X is the
process ID of the xend process ["python xend start" or similar]. At
least you may have a chance of seeing why xend dies.
