We've upgraded Mathematica from 8.0.4 to 10.0 and now 10.0.1. Running on a 64bit Debian Wheezy-Server, sometimes about every 3rd startup sees MathKernel dying (there are 2 at startup, one MathKernel -sandbox
, one MathKernel -mathlink
; the later dies), and in the console we get
LinkConnect::linkc: -- Message text not found -- (LinkObject[btkfn_shm, 3, 1])
(The symbol btkfn_shm changes each time, of course.) The frontend continues to work, however, evaluations are not possible. If we start Mathematica and have it run an evaluation right away, apparently, short evaluations are done. But in general, until the kernel dies and we see the error message we can't do much more than enter 1 or 2 commands.
We tried it with ssh -X
and within a VNC session. This seems to make no difference. A web research suggested to make sure the loopback interface is available, but that's the case. iptables exist but do not block localhost. We tried -clean
, -cleanStart
, and -dv
, too.
Mathematica 8.0.4 still works fine. Running only the kernel with math
works also.
Could this be an issue with the license server (we connect to our university's license server) since it seems to happen more frequently at times!? Like during the day. And right now, 6 p.m., I had 30 startups with no problem. If it's related to the license server, how could I debug this?
