[Olympus developers 456]: Re: Audio Server keeps crashing, the application also stops.

[Nitin Dhawan]

We have made some progress on this. The problem is not with Sphinx. The
"decoding server is invalid" is a standard message before the sphinx server
is found and connected to.

 

But the audio server keeps crashing intermittently. The windows even viewer
Log (Event ID 1000) is

We are running this on Windows 7 and Windows 8 environments. It seems like a
memory creep issue.  Now we are trying to recompile this on Visual Studio 13
with 64 bit  , and hope that this works.

Subject: Audio Server keeps crashing, the application also stops.

 

We are facing this problem on all  test machines that the Audio server keeps
crashing after working for a few seconds. The whole application also stops.
We noticed in the log that it is unable to connect to the PocketSphinx
server for some reason. 

 

Any ideas?
