[ts-gen] order execution and connectivity problem

[Nils Gebhardt]

I get some strange connectivity behavior. I have a script which fires an
order, as it appears in the following log lines (sorry for bad line
wraps): 

Oct  8 08:30:58 vneumann : 27815|30657|   5137123|2|26| 0|
order(42,TRAIL,Submit,1,0.00,0.07,0);|
Oct  8 08:30:58 vneumann : 27815|30657|   5137201|3| 3|15|1|        43|
MKT|SELL|FUT.SMART.GBM.
Oct  8 08:30:58 vneumann : 27815|30657|   5463744|3| 3|15|2|        42|
TRAIL|BUY|FUT.SMART.GBM.

However, the next entry in the log is

Oct  8 09:10:09 vneumann : 27815|33009|2099191087|3| 4| 2|      -1|1100|
Connectivity between IB and TWS has been lost.|
Oct  8 09:10:10 vneumann : 27815|33010|2100191862|3| 4| 2|      -1|2103|

repeating ca 200 times with OK and broken messages:  

Oct  8 09:10:11 vneumann : 27815|33011|2101030535|3| 4| 2|      -1|2103|

then finally the orders are executed 40 minutes later: 

Oct  8 09:10:28 vneumann : 27815|33028|2117242444|3|11| 4|1|GBM|FUT|
20071206|0.0||DTB|EUR|FGBM DEC 07|0000e7d2.4522069a.01.01|20071008

PreSubmitted|0|1|0.0|1252408757|0|0.0|27815|

so essentially in terms of the market that means that the original order
is not executed and there is some ghost market order at some undefined 
point in time later on. For a productive system this is a somewhat
uncomfortable behavior. 
Has anybody a hint what might be the reason behind this and how to make
the connection more reliable? 


Thanks
