When I get this, my only recourse is to reboot the server. I watched an MS webcast on this error and they say it's a kernel mode driver not releasing memory. The webcast goes on to provide all sorts of useful (and time intensive) steps to figure out which driver is causing the problem. I get this error mostly on my PDC Emulator. adam "Schneider, Chad M" <CMSchneider@Bemi To s.com> thin@xxxxxxxxxxxxx Sent by: cc thin-bounce@freel ists.org Subject [THIN] Handful of servers.... 12/01/2005 11:27 AM Please respond to thin@xxxxxxxxxxxx g Thursdaysâ I get thisâ The server was unable to allocate from the system paged pool because the pool was empty. W2K SP4 PS 4.0 Once that error begins, users can not connect to the server anymore. I knock a few users out, all is well. Chad Schneider Technology Analyst/Citrix Admin.
