You said it wasn't a swap space issue, but as Perderabo suggested take another close look at that, and if you have more than one swap space, there's no real guarantee which one will be selected at any point in time.

The first issue, can't fork, almost sounds like you need to do some kernel tweeking. The database owners should be able to give you some ballpark kernel settings, however thats all dependant of DB size, how much/how often updates, queries take place for your installation; however they should be able to give you some min. settings. If you've not already tweeked these, max_thread_count might be a place to look, however there are many other paramaters worth looking at. Doing in a production envoriment is not ideal. Definately document well, what your original setting were, and exactly what was changed. Best done with someone with some experience with kernel tuning.

nissetup(8)						      System Manager's Manual						       nissetup(8)

NAME
nissetup, ypsetup - Sets up the Network Information Service (NIS) environment SYNOPSIS
/usr/sbin/nissetup /usr/sbin/ypsetup DESCRIPTION
The nissetup (formerly ypsetup) script configures and runs NIS on your system. You can use nissetup to initially set up your NIS configura- tion, to change your current NIS configuration, or to remove your NIS configuration. NIS provides a distributed data lookup service for sharing data among networked systems. Before running nissetup, make sure that your system is connected to a local area network and that the network is configured and running. You must know the name of your NIS domain and your system's role in the domain (master server, slave server, or client). Security Note You invoke nissetup from the SysMan Menu. See sysman(8) for more information. When using the nissetup script to set up a NIS server that is running with enhanced security, you must answer yes to the question about locking the domain name and authorized servers (the ypbind -S option). If you are setting up a master server, the server is bound to itself (done by default). If you are setting up a slave server, the server is bound to itself done by default) and optionally to the master server and any other slave servers. If your system will be the master server for your NIS domain, be sure no other master exists for your domain and that the NIS database files are in the /var/yp/src directory. Note Remove the root entry, if it exists, from the passwd database file. If your system be will be a slave server or client, be sure a master server is already set up for your NIS domain. FILES
