AMQ9557E: Queue Manager User ID initialization failed for 'sv08914'.

EXPLANATION:
The call to initialize the User ID 'sv08914' failed with CompCode 2 and Reason
2035. If an MQCSP block was used, the User ID in the MQCSP block was ''. If a
userID flow was used, the User ID in the UID header was '' and any CHLAUTH
rules applied prior to user adoption were evaluated case-sensitively against
this value.
ACTION:
Correct the error and try again.

Not sure if this is helpful
I would speculate that this is the username of the application sv08914
To find the name of the application you may have to search in the intranet of your working environment.
One could also search in the rest of the error log for sv08914, you may or may not spot a mapping into an IP address.
