We are currently using STAF's Queue Service to send data between processes 
running on both the same machine and remote machines. The data we are sending 
back and forth consists of a dictionary of varied types, i.e. a dictionary 
which may contain other dictionaries, lists, etc. This dictionary is converted 
to a string from which the message is constructed.  We have been doing this for 
sometime with no problem. Recently we have been having problems with a new 
dictionary which is much larger than ones we have used in the past. As soon as 
we attempt to queue the message, we have problems. i.e. the python process 
aborts, our error messages and staf log messages are cut off, and all 
communications via tcp/ip is lost. The computer crashes and has to be rebooted. 
Since we have used this successfully to date the questions are:

 

1.      Is there a limit to the size of message which can be sent using STAF's 
queue service.
2.      What is the largest message size allowed?
3.      Is this limit configurable?
4.      If so, how is it configured?

 

Thanks,

Norma
