connection problem

Hi everyone, did someone meet the following issue? We use Informix Online 5.00 UC2 on a Unix box (AT&T UNIX SYSTEM V Release 4.0). Currently only 91 users can connect to the database. Afterwards no new user can login - till someone logs out and the user can connect to the server, Informix fires error messages (see below). We tried to tune the operating system according to a 7.23 machine notes (http://www-3.ibm.com/software/data/informix/pubs/library/notes/machnote/ncr/723uc1nc.htm). However this didn't resolve the issue. The following error message is sent by Informix Star: sqAU0BPQAAsqlexec Szoszi kkieg -p sqAU0BPQAAsqlexec Szoszi kkieg -p 25519 The sqlexecd daemon cannot open the network device.: System error: No space left on device 25519 The sqlexecd daemon cannot open the network device.: System error: No space left on device 25519 The sqlexecd daemon cannot open the network device.: System error: No space left on device 25519 The sqlexecd daemon cannot open the network device.: System error: No space left on device 25519 The sqlexecd daemon cannot open the network device.: System error: No space left on device 25519 The sqlexecd daemon cannot open the network device.: System error: No space left on device 25519 The sqlexecd daemon cannot open the network device.: System error: No space left on device 25519 The sqlexecd daemon cannot open the network device.: System error: No space left on device 25519 The sqlexecd daemon cannot open the network device.: System error: No space left on device sqAU0BPQAAsqlexec Szoszi kkieg -p Any hint, help would be highly appriciated.
