I'm using JMS w/ MQ v6.0 to publish to a series of topics for distribution. Most topics publish just fine, occasionally one or another message fails to go publish ( MQ accepts the message, but never publishes it publicly ) but one topic fails to go through ever.

I've tested each character combination shown below in turn, beginning with the full 190 character length string( trucated for brevity ) below. There is no dead letter, nothing in the error log that corresponds in time or frequency, no JMS exception, nothing to indicate a problem except that the message fails to publish.

original topic:
NLS/EventType=MobileViewEvent/Version=1.0/Company=web-boeing-com/AssetOwner=LPO_XYZManuf_BRAIDSS/Site=35/Building=Forward Structures WS2 - Skinning/Floor=/Zone=Inner Wing WS4 - FAS Drilling/;
There is no consistent rule that is apparent to me.
One of the truly odd situations is that 'Zone=Inner Wing W' goes thru, but nothing else until 'Zone=Inner'.
Also, if you remove spaces from the Zone field, but leave them in the Building field, MQ accepts it.

All of these topics to fail to publish:
.../Site=35/Building=Forward Structures WS2 - Skinning/Floor=/Zone=Inner Wing WS4 - FAS Drilling/;
.../Site=35/Building=Forward Structures WS2 - Skinning/Floor=/Zone=Inner Wing WS4 - FAS Drilling;
.../Site=35/Building=Forward Structures WS2 - Skinning/Floor=/Zone=Inner Wing WS4 - FAS Drillin;
.../Site=35/Building=Forward Structures WS2 - Skinning/Floor=/Zone=Inner Wing WS4 - FAS Drilli;
.../Site=35/Building=Forward Structures WS2 - Skinning/Floor=/Zone=Inner Wing WS4 - FAS Drill;
.../Site=35/Building=Forward Structures WS2 - Skinning/Floor=/Zone=Inner Wing WS4 - FAS Dril;
.../Site=35/Building=Forward Structures WS2 - Skinning/Floor=/Zone=Inner Wing WS4 - FAS Dri;
.../Site=35/Building=Forward Structures WS2 - Skinning/Floor=/Zone=Inner Wing WS4 - FAS Dr;
.../Site=35/Building=Forward Structures WS2 - Skinning/Floor=/Zone=Inner Wing WS4 - FAS D;
.../Site=35/Building=Forward Structures WS2 - Skinning/Floor=/Zone=Inner Wing WS4 - FAS ;
.../Site=35/Building=Forward Structures WS2 - Skinning/Floor=/Zone=Inner Wing WS4 - ;
.../Site=35/Building=Forward Structures WS2 - Skinning/Floor=/Zone=Inner Wing WS4 -;
.../Site=35/Building=Forward Structures WS2 - Skinning/Floor=/Zone=Inner Wing WS4 ;
.../Site=35/Building=Forward Structures WS2 - Skinning/Floor=/Zone=Inner Wing ;
.../Site=35/Building=Forward Structures WS2 - Skinning/Floor=/Zone=Inner Wing;
.../Site=35/Building=Forward Structures WS2 - Skinning/Floor=/Zone=Inner Win;
.../Site=35/Building=Forward Structures WS2 - Skinning/Floor=/Zone=Inner Wi;
.../Site=35/Building=Forward Structures WS2 - Skinning/Floor=/Zone=Inner W;
.../Site=35/Building=Forward Structures WS2 - Skinning/Floor=/Zone=Inner ;

All of these topics succeed in getting published by MQ:
.../Site=35/Building=Forward Structures WS2 - Skinning/Floor=/Zone=Inner Wing WS4 - F/;
.../Site=35/Building=Forward Structures WS2 - Skinning/Floor=/Zone=Inner Wing WS4 - FAS;
.../Site=35/Building=Forward Structures WS2 - Skinning/Floor=/Zone=Inner Wing WS4 - FA;
.../Site=35/Building=Forward Structures WS2 - Skinning/Floor=/Zone=Inner Wing WS4 - F;
.../Site=35/Building=Forward Structures WS2 - Skinning/Floor=/Zone=Inner Wing WS4;
.../Site=35/Building=Forward Structures WS2 - Skinning/Floor=/Zone=Inner Wing WS;
.../Site=35/Building=Forward Structures WS2 - Skinning/Floor=/Zone=Inner Wing W;
.../Site=35/Building=Forward Structures WS2 - Skinning/Floor=/Zone=Inner;
.../Site=35/Building=Forward Structures WS2 - Skinning/Floor=/Zone=Inne;
.../Site=35/Building=Forward Structures WS2 - Skinning/Floor=/Zone=Inn;
.../Site=35/Building=Forward Structures WS2 - Skinning/Floor=/Zone=In;
.../Site=35/Building=Forward Structures WS2 - Skinning/Floor=/Zone=I;
.../Site=35/Building=Forward Structures WS2 - Skinning/Floor=/Zone=;
.../Site=35/Building=Forward Structures WS2 - Skinning/Floor=/Zone;
.../Site=35/Building=Forward Structures WS2 - Skinning/Floor=/Zon;
.../Site=35/Building=Forward Structures WS2 - Skinning/Floor=/Zo;
.../Site=35/Building=Forward Structures WS2 - Skinning/Floor=/Z;
.../Site=35/Building=Forward Structures WS2 - Skinning/Floor=/;
.../Site=35/Building=Forward Structures WS2 - Skinning/Floor=/Zone=Inner_Wing_WS4_-_FAS_Drilling/;
.../Site=35/1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3;

Has anyone seen any topic related problem like this? Thanks!

Could it have to do with some limitation to topic length?
Or would you need to use "" with a topic containing spaces to have coherent behavior??

Topic length does not appear to be a factor. I have messages publishing fine to topics over 200 characters. Some of the topics that fail are shorter than others that succeed. Also, if I use just numbers for the final 30 or so characters, it publishes fine.

Topic length was the first thing we checked.
