Apache, PHP+Informix on Windows NT 4.0 Server - memory allocation

Hello! I run Apache in 1.3.22 version, PHP 4.3.1 with Informix module. I have it on two machines: a) Windows NT 4.0 Workstation + SP 6.0 b) Windows NT 4.0 Server + SP 6.0 The same PHP scripts on a) it works perfectly, but on b) when I try to connect to Informix server (on Unix SCO) I got "Warning: ifx_connect(): E [SQLSTATE=IX 000 SQLCODE=-461] in c:\program files\...\errors\choice.php on line 26" Informix documentation describes "-461" error as "File open error. The database server could not open a file required to execute this statement. Sometimes this is a general error, possibly referring to a message file that the database server cannot find. At other times this error occurs because the locator (blob) structure field loc_loctype was set to LOCFNAME, but the database server could not open the file using the pathname in loc_fname and the flags in loc_oflags. Any of the following conditions can cause the database server to report this error: * An environment variable setting is missing. * Not enough disk space is available for opening the file. * A file permission problem exists. * The limit on the number of open files was reached. * The database server could not access a blob of type LOCFNAME. * The database server is on a different machine from the client. * The statement transfers a value between a file and a BYTE or TEXT column. * The statement attempts to drop a database when a required file is not available. Make sure your environment variables and file permissions are set correctly. For more information, check for any accompanying ISAM error code or operating-system message." I have enviroment variables and file permissions set on b) machine, have enough of disk space. What may be a reason?
