Due to # constraints in loader(8) on i386, this must be a multiple of 4. # 256 = 1 GB of kernel address space. Increasing this also causes # a reduction of the address space in user processes. 512 splits # the 4GB cpu address space in half (2GB user, 2GB kernel). # options KVA_PAGES=260 If that doesn't help, you may also consider trying 4.8-RELEASE or -STABLE; I believe that some additional changes to fix handling of 4GB machines were committed after 4.7-RELEASE. (You'll have to search the mailinglist archives to confirm this, I can't remember exactly when they occured.) Also, how are you exhausting 128K sockets to do a test of 2000 simultaneous connections? Are the rest all in the TIME_WAIT state? Mike "Silby" Silbersack
