Subject: excessive ioc memory utilization

Hi,

When I came in this morning our high voltage iocs are using excessive amounts of memory, around 95%. They are all mv2301 processors with 16MB of memory running epics 3.14.6 built with vxworks 5.5.1. The netStackSysPoolShow and netStackDataPoolShow outputs are reasonable. There are not an excessive number of channels connected. What can I use to look and see where the memory is allocated? Any other suggestions?

Thanks, Geoff
