Symptoms

Resident memory of +APX process seems to be leaking; it is increasing slowly but steadily and is now over 1.1 GB.

RSS_MEM_usage by PID 82243 is Warning! <Server Name>: oracle_82243_+a Process size
is 2049 MBytes. oracle+APX3 (LOCAL=NO)
RSS_MEM_usage by PID 355161 is Warning! <Server Name>: oracle_355161_+ Process
size is 2049 MBytes. oracle+APX4 (LOCAL=NO)


Looking at the process trace files, the OEM agent appears to be the culprit as the module name/action name below appears 4,00 times in the trace file:

*** MODULE NAME:(emagent_SQL_osm_proxy) 2018-08-01T15:26:58.809877+10:00
*** ACTION NAME:(Single_Instance_OFS_Summary) 2018-08-01T15:26:58.809903+10:00

PGA memory growth observed with long running backgrounds such as APX, MMON that runs periodic x$kf queries on ASM instances.

Permanent Memory growth for backgrounds of type -
