Pre-processor failed to start in HANA.

Hi Team,

When we issued a HANA restart sometime last week, we got an error saying

FAIL: process hdbpreprocessor HDB Preprocessor not runnin

No much details in log files too.

Then i tried a manual start of preprocessor, it failed with an error saying

Crash at /HDB/IMP/NewDB100_REL/src/sys/src/Basis/System/impl/ProcessID.cpp : 1194 Reason: bind failed with errno: 28.

I had checked at OS level this port was not bound to any  process, So i rebooted the host and issue was fixed.

Any idea why is this?

Thanks.
