Issue/Introduction:

The FT secondary SpectroServer crashed during an online backup due to high incoming trap rate. The stack in the crash file shows a user model read when doing a landscape find:

libsskrnl!CsLandscape::find+0x1f

libsskrnl!CsVnmProxyEventLogMgr::read_user_model_info+0x29

libgserv!CsProxyEventLogMgr::gen_event+0xfa

libgserv!CsDisconnectMgr::disconnect+0x186

libgserv!CsConnectionMgr::close+0x184

libgserv!CsConnectionMgr::shutdown+0x183

Cause:

Overloaded SpectroSERVER due to high incoming trap rate

Environment:

Release : 10.3

Component : Spectrum Core / SpectroSERVER

Resolution:

The crash will be fixed in a future release of Spectrum. The workaround is to allocate more memory to the OS for the secondary SpectroSERVER and reduce the incoming trap rate to the secondary SpectroSERVER.

Additional Information:

US570489 by defect DE386636 to redesign the trap processing code to prevent this crash after OLB.
