2350960 - Failed to assert 'read->sqmr_blk_offset < sizeof(read->sqmr_block->sqmb_data - SRS

Symptom

  • Stack trace in SAP Replication Server (SRS) may look different depending on the setting of 'parallel_dist', but always contains 'Failed to assert 'read->sqmr_blk_offset < sizeof(read->sqmr_block->sqmb_data)' at 15674'

 

If parallel_dist is enabled the stack looks like the following:

N. 2016/08/02 06:40:41. INTERNAL ERROR #23 WORKER( ) - generic/sqm/sqmext.c(15672)

When parallel_dist is disabled the stack trace looks like the following:
