The ' thread number' column must be displayed in order to correctly read the trace knowing which 'connection' is working and finding out how each program runs.
Each session has a constant thread number.
Example:
00000354 Waiting
connection
00000354 Waiting connection
00000414 LAUNCHER/400 V:Launcher server version 2.0.0.0 - running as
Service
00000414 Connection accepted
00000414 Messages processing started
00000354 Waiting connection
0000034C LAUNCHER/400 V:Launcher server version 2.0.0.0 - running as
Service
0000034C Connection accepted
0000034C Messages processing started
0000034C >CRITSECT,Opt=
0000034C *ACK
00000414 >WORDOPEN,Opt=
00000414 LNC/Word Module=C:\progra~1\launcher400\LNCWORD.dll; V.2,0,0,0
00000414 MS Word V.9.0
00000414 *ACK
In this case two sessions are opened: threads '414' and '34C'.
