CogServer stops logging messages

[Nil Geisweiller]

Hi,

in the context of ros-behavior-scripting sending netcat messages to the
cogserver, there is what appears to be a crash, see the log

[2016-07-20 14:06:32:461] [DEBUG] [ConsoleSocket] OnLine
[(EvaluationLink (PredicateNode "visible face") (ListLink (NumberNode
"14996")))]
[2016-07-20 14:06:32:461] [DEBUG] params.size(): 7
[2016-07-20 14:06:32:461] [DEBUG] Unknown opencog::Request command:

[2016-07-20 14:06:32:461] [DEBUG] [ConsoleSocket] OnLine [scm]
[2016-07-20 14:06:32:461] [DEBUG] params.size(): 1
[2016-07-20 14:06:32:461] [DEBUG] Creating opencog::Request instance

[2016-07-20 14:06:32:461] [DEBUG] [Request] setting requestResult:
0x7fd01c001a70
[2016-07-20 14:06:32:461] [DEBUG] [ConsoleSocket] OnLine request scm is

[2016-07-20 14:06:32:462] [DEBUG] [ConsoleSocket] OnRequestComplete

console socket receives the EvaluationLink, but then never seems to
process it and entirely stops logging messages (after that last one
above). Meanwhile the PLN reasoner running in the background is still
able to fetch the atomspace and log messages about it.

Sometimes, rarely, it manages to go passed that and keep logging
messages like

[2016-07-20 13:32:20:818] [DEBUG] [GenericShell] line disc: expr, len of
93 ='(EvaluationLink (PredicateNode "name") (ListLink (ConceptNode
"7157") (ConceptNode "20839")))'

and when that occurs the PLN reasoner can indeed find the added
Evaluation Predicate "name" ...

Any idea?

Thanks,
Nil

P.S: there are already many github issues about the demo, I'm not sure
how it may relate to other issues.

Hi Nil,

 Linas was fixing lot of issues with cogserver, for some reason I have stuff crash at random rare occasions on my machine, but I am not able to replicate it at will. For amen, the system crashes frequently, i thought that was isolated issue, but I am not sure what to say. On my system for majority of the time the code works without problems. 

Regards,

Mandeep
