WAAE 11.3.6 SP4_CUM1 on windows CA WA Agent for SAP R11.3.4, Build 56
Cause
The 'Negative seek offset' exception occurs when Agent process the MGMTMETRIC GET request (MGMTMETRIC GET MBean(tcpip.channel.sap_sch) Attribute(target.pending.list)). The Agent attempts to access the transmitter queue database (transmitter_queue_spool_*.odb) for the manager specified to retrieve the list of pending wobids. The .odb file seems to contain only records that are marked for removal/deletion, so file offset is invalid which results in java exception.
