Fixed In:
13.1.0, 12.1.3.4
Opened: Aug 16, 2017 Severity: 2-Critical
While writing large query results from AD server to sessionDB using memcache API, write operation fails with partial write.
Operation fails with partial write. All worker threads performing authentication eventually gets locks down. Session watchdog thread eventually make a forced abort to recover from the situation. Apmd restarts in this situation.
Large volumes of AD query (with Required 'All Attributes') results from AD server while writing to SessionDB.
Make query for specific attributes not the option 'All Attributes'.
Partial write failure has been fixed, by writing remaining parts of the query results in several iterations, till the entire result is written.
