UCA CWLLG0203E Errors - General Questions


Hi ,
I was wondering if someone answer a couple of question with respect to UCA errors and their impact on the BPM platform? I did not open a PMR and collect must gathers as we literally have logged thousands of the kind of errors seen below since February:
> [5/29/15 1:56:59:675 PDT] 0000012d wle_scheduler E CWLLG0203E: Undercover Agent job failed. Task 27440706 job details are: class=com.lombardisoftware.bpd.runtime.engine.quartz.DbNotificationBpdTask parameters=[1360581;14432099] Error: [<41message:String or binary data would be truncated.><121flowObjectID:/25.75d9a293-210b-42a2-a871-7938c12aa4be//bpdid:1bf8c098705e02a5:-25d9311e:13381e78200:-7ff4/Step (Send email to Shopper)>]
[5/29/15 1:56:59:691 PDT] 00000281 wle_scheduler E CWLLG0181E: An exception occurred during execution of task 27,440,651. Error: [<47message:Not a valid char constructor input: in_creation><112flowObjectID:/25.4ece546e-a737-4901-bbb4-f6d6a6c2226e//bpdid:18b61ee94d64e675:-54abfa3:138d25b6985:-7f3d/Step (UI Process CR)>]
Sometimes we may see as few as 5-10 / day or as many as 30+/day. No way to tell when they will occur.
The general questions are:
1. Do these errors in anyway impact the performance of BPM, in so much as, if we accumulate ~200/week will that eventually bring the system down?
2. Are the applications causing the UCA's to error? i.e. we see all kinds of different reasons in the logs from passing wrong dates, data that is in the wrong format, null....etc.
OR
3. Are these normal BPM related (Not application) issues?
In the above case - looks like a problem with some data needed to send email to shopper? Not sure and do not really care as this is just a general set of questions; as stated, we see ALL kinds of different situations that throw CWLLG0203E errors - above sample is a sample of just one kind.
We are trying to troubleshoot and feel it may be application related but have no clear way to conclusively determine if it is code; plus the programmers (contractors) have gone. Also, I read a few articles that lead me to believe it could be system related due to out of sync system clocks (do not believe that's the case as we use NTP servers in our data centers). Would be sincerely grateful for any ideas/suggestions to point us in the right direction.
These are going to be application level issues. If a UCA fails due to bad data then your developers should go back through the code and fix to proper data is checked or sanitized in some way.

Generally this UUID string is not helpful and you would need to search for it in your TWX examples.

if you have many apps this may not be easy. A search through the DB would be needed. I do not have this query public at this time.
For example on some javaScript errors you may see something like this post.

Thank you Mark great answers and link - was wondering about this question.

I am sure it impacts the application - I am more concerned with these UCA errors potentially taking PRODUCTION down, since we see so many of them.
Kindest Regards,

Impact performance - no not really, other than this part of the application is broken.
No, should not bring down a system. These are just UCA failures, after 5 attempts they will stop and fail. The application is broken so the users may see delays in progressing tasks or not see new data or updates in a timely fashion until the code issue is resolved.
I suggest installing or upgrading to get JR47860. This will catch UCAs which fail and make them available to be replayed with BPMReplayOnHoldEMTasks. If not, they will be discarded. See This post here
