I have this error message with my informix db, the error is:

listener-thread: err = -25571: oserr = 0: errstr = : Cannot create an user thread. On NT check username, and IXUSERS group.

when the error ocurrs, theinstance is blocked; I'm using Informix:IDS 9.40-FC4 runing on Solarins: 5.8, the ONCONFIG is: NETTYPE         tlitcp,4,150,CPU

Kernel configuration
ndd -get /dev/tcp tcp_conn_req_max_q0
1024
ndd -get /dev/tcp tcp_conn_req_max_q
128

also I have 106 active conections, 256 total, 133 maximum concurrent
the diary average is 100 to 700 conections

some idea?

You cannot have 700 connections in current setup, only 600

try
NETTYPE soctcp,8,200,cpu

what is the output of onstat -p and onstat -g glo? (after my change)

Can I have full onconfig for review?

or better:

NETTYPE soctcp,8,200

for class to be selected automatically. -g glo will show class used.

Also
NUMAIOVPS <no value>

Makes sytem auto-tuning.

NUMCPUVPS must be CPU-1

Rule of a thumb is to have twice times CPU count 200-connection network processes.
Never ever try more than 200 connections per net process. Do not run SHM connections alongside NET connections.

m=1 option makes informix ODBC driver to reuse connections for more SQL statements - maybe this helps your cause.
