i recently installed freebsd-2.1R, and since supped -stable, compiled a new kernel and set of libraries. since then i've been having the following problem: i get an error that i cannot fork a new process (actually, as root i usually can, but not always -- i guess this is supposed to protect against denial of service attacks...anyway....). i thought at first that this was due to the fact that the libraries had changed on a live system, so i baked a new kernel (i set the max users up to 40 in case the process table was running out?) and rebooted. 24 hours later i'm having the same problem! help please, i don't want ot have to reboot every day! verbatim: zsh: fork failed: resource temporarily unavailable [92] (though, the number 92, i'm quite sure, is different from yesterday. i think it was 250 or something yesterday...) (also, there are nowhere near 20 + 16 * 40 processes running right now -- actually there are 62 -- speaking of which, that seems to be my new hard limit =( ....until i reboot, at least.) system: 486-80Mhz, 48MB RAM machine "i386" cpu "I486_CPU" ident "EUTHYPHRO" maxusers 40 options INET #InterNETworking options FFS #Berkeley Fast Filesystem options NFS #Network Filesystem options MSDOSFS #MSDOS Filesystem options PROCFS #Process filesystem options "COMPAT_43" #Compatible with BSD 4.3 options "SCSI_DELAY=5" #Be pessimistic about Joe options BOUNCE_BUFFERS #include support for DMA b options UCONSOLE #Allow users to grab the c options SYSVSHM options SYSVSEM options SYSVMSG config kernel root on sd0 controller isa0 controller fdc0 at isa? port "IO_FD1" bio irq 6 drq 2 vect disk fd0 at fdc0 drive 0 controller wdc0 at isa? port "IO_WD1" bio irq 14 vector wd disk wd0 at wdc0 drive 0 options ATAPI #Enable ATAPI support for IDE bus device wcc1 #IDE CD-ROM controller aha0 at isa? port "IO_AHA0" bio irq ? drq 5 vec controller scbus0 device sd0 # syscons is the default console driver, resembling an SCO console device sc0 at isa? port "IO_KBD" tty irq 1 vector sci # Enable this and PCVT_FREEBSD for pcvt vt220 compatible console d #device vt0 at isa? port "IO_KBD" tty irq 1 vector pcr #options "PCVT_FREEBSD=210" # pcvt running on #options XSERVER # include code for device npx0 at isa? port "IO_NPX" irq 13 vector npxint device sio0 at isa? port "IO_COM1" tty irq 4 vector si device sio1 at isa? port "IO_COM2" tty irq 3 vector si device lpt0 at isa? port? tty irq 7 vector lptintr # Order is important here due to intrusive probes, do *not* alphab # this list of network interfaces until the probes have been fixed # Right now it appears that the ie0 must be probed before ep0.
