While troubleshooting an issue with a damaged embedded database table, I noticed that nearly all of the 12 GB of memory was being used, according to Task Manager. Had not noticed this before, so I was concerned when the database fix did not resolve this.
A boot would clear it up for hours (usage drops to two, three or four GB mostly) but typically by the next day memory was all used again.
Oddly, Task Mgr says all the RAM is used, but the processes displayed are obviously not using it (not adding up to anywhere near 11.5 GB). Hidden processes maybe?
SEP 12.1.1000 running on Win 2008r2.
Maybe others experience the same but I could not find any posts on it. This thread has some similarities though: https://www-secure.symantec.com/connect/forums/database-high-memory-utilization-sep-121
