Subject: [ISSForum] issCSF.exe eating up virtual mem
One of my server sensors (6.5 service release 3.6) is eating up virtual memory on windows 2000 server.....from approx 36mb to 1GB!!........
The process eating up VM is issCSF.exe I have to reboot (or stop and start issdaemon) about once a week.
Has anyone experienced this before?
