Our SBS with Exchange has developed a strange problem. After having remote email, server access, and server lockups, we would find a long string of "Event ID: 2019 The server was unable to allocate from the system paged pool because the pool was empty" messages. At first, we would restart the server and everything would be fine for a few days. Then all of a sudden the Event ID: 2019 (and occasionally 2020) message would show up again. We had downloaded and installed Symantec Mail Security for SBS about a month ago. We recently implemented their spam filtering, and it seems that the problem showed up right after that. I called Symantec and they asked if we were running NAV. We had been, but removed it to install Mail Security. Symantec says they don't believe their program is the problem source, but said we could download and install the latest revision of Mail Security just to be sure. Symantec believes the problem is a memory leak, and it may be a Microsoft problem. -- That's when I decided to post the problem here. Has anyone seen this problem before? Any help will be greatly appreciated. Thanks.
