DESCRIPTION:
After making some firmware changes, and adding another application, the client can no longer connect to the CLS in single-threaded mode. Tracing showed the following:

The customer increased the working set sizes and page file quotas in the set server logicals for the CLS server,
however, this had no effect.  The reason is, the program dmq$cls_ucx is creating a temporary command 
procedure in cls_creproc.c to create the subprocess and this procedure has hardcoded values for
"WORK/LIM=1500/QUOTA=1024/EXT=4096" and is doing a set working set size change the sizes back to very small
number, see the log:

"CLS_S_15007_003"
Also, searching the dmq$cls_ucx.exe files shows the command $ SET <>
<> 
WORK/LIM=1500/QUOTA=1024/EXT=4096 embedded in the executable.
These values are hardcoded in cls_creproc.c .
