Hi @ADNAN, 
Thank you for using IFS Community, I noted this was a post that hasn’t received a response for a long time and was wondering if you were able to resolve this issue? 
Regarding the WARNING: too many parse errors, count=XXX SQL hash=XXX
it occurs due to incomplete SQL being continually sent to the database by the application. If you observer almost all of the errors are for hash=0Xdd4c26ef: So fixing the incomplete SQL that is being sent to the database should help in resolving the concern. If not may need to investigate further into the logs.

I have seen the same error in the oracle alert log (with different user ID) has been reported by one of Swedish customers as well. Initial investigation has revealed that it was related to the Global Extension called e-Ledger for Turkey. I can see IFS Support are investigating it but the root cause for this has not been identified yet.
