We get the same "Resource temporarily unavailable" also on AIX 4.3.3.
 I'd be interested if you get this resolved.

$ ulimit -a
time(seconds)        unlimited
file(blocks)         2097151
data(kbytes)         131072
stack(kbytes)        32768
memory(kbytes)       32768
coredump(blocks)     2097151
nofiles(descriptors) 8096

We have maxprocs set to 500.  Lsoft tech support suggested "try
increasing nofiles to 4096 and see if that makes a difference."
We also have to restart lsv from time to time when it quits responding
to the web interface.
