It is rather brute force but matches your decision to skip rollbacks: 

while $TLEVEL { TCOMMIT }

to be sure to catch all cases I'd place it in a  %ZSTOP.mac 
It's the reverse of %ZSTART.    >>  docu

Do you still expect some echo?
Or is the question meanwhile just out of date?

at first sight, it looks like an issue on variable scoping with embedded SQL
a quite old issue
try %suspendedCount instead of suspendedCount
 

&sql(SELECT count(ID) into :%suspendedCount FROM Ens.MessageHeader where TargetQueueName not like '_S%' and TargetQueueName not like 'ENS%' and Status='Suspended' )
resulting  0 into suspendedCount

Do you still expect some echo?
Or is the question meanwhile just out of date?

 
USER>set s1=111,s2=444
USER>set a(s2_$c(0),s1_$c(0))=77
USER>set a($c(0)_s1,$c(0)_s2)=99
USER>zwrite
a("111","444")=99
a("444","111")=77

"save it from the class " ?  whatever that may mean .... ?

SendRequestSync   is an object method that requires an object as the base.
##class(Ens.BusinessService).SendRequestSync(   works for ClassMethods only.
You need an object instance of Ens.BusinessService to call it.
##class(Ens.BusinessService).%New().SendRequestSync( 
might be a dirty workaround

• %XML.GlobalCharacterStream  extends %Library.GlobalCharacterStream
• therefore it has method FindAt()

method FindAt(position As %Integer, target As %CacheString, ByRef tmpstr As %CacheString = "", caseinsensitive As %Boolean = 0) as %Integer

Find the first occurrence of target in the stream starting the search at position. It returns the position at this match starting at the beginning of the stream. If it does not find the target string then return -1. If position=-1 then start searching from the current location and just return the offset from the last search, useful for searching through the entire file. If you are doing this you should pass in tmpstr by reference in every call which is used as a temporary location to store information being read so the next call will start where the last one left off. If you pass caseinsensitive=1 then the search will be case insensitive rather than the default case sensitive search.

Copy to String may help but is limited by MAXSTRING size.
There you may use [  (=contains OPERATOR) or $FIND() function
Don't mix up SQL predicate %CONTAINS  with [  (string contains operator)
