Error messages in the E1 HTML Server logs - WLS

Hi,

The e1root.log is generating messages with BSFN ending with errors in the E1 HTML Server logs on the Weblogic Server 11g. The log file is growing quickly and generating too many files logs.
Apparently these BSFN use memory cache,  so I'm suspecting that this is the problem.

Some BSFN examples:
Appl    BSFN
P4113   TransferProjectComitmentCache
P31114  F4111ClearDetailStack
P3002   CacheBOMHeaderMBF
P3002   FreePtrToDataStructure
P48013  F4801ClearWorkFile
P4310   DeleteClausesTableRecords

Log example (these messages appear thousands of times by 3 to 5 minutes, generating too many log files):
