Mark,

 

This may be launch-pad bug 717252; see also the R3.14 known problems page (linked below).

With sufficient thrust, pigs fly just fine. However, this is

not necessarily a good idea. It is hard to be sure where they

are going to land, and it could be dangerous sitting under them

as they fly overhead. -- RFC 1925

Subject: PyEpics segmentation faults

 

I'm running PyEpics 3.0.11, on Ubuntu 10.04.2, Epics 3-14-12, Python 2.6.5, linux-x86_64. A while ago (perhaps with earlier versions of something?) everything seemed to be working fine. I hadn't used it for a while, but now when I fire it up I end up with weird behaviour, e.g.:

 

-I type: Motor('XXX:m1'). Returns error, saying 'XXX:m1' is not a motor.

 

-I type: Motor('XXX:m1') a second time. This one works.

 

-Sometime later, I'll get a 'Segmentation fault'.

 

Anybody seen this kind of behaviour? Any ideas what's going on or where I should start looking for solutions?

 

P.S., I just tried with Python3.1. Same thing.

 

Thanks

Mark
