Problems using named pipes in the sql.ini file

[Bug #241136] If you use named pipe entries in the sql.ini file, Adaptive Server does not work, and you may see stack traces containing functions such as nmp_nopen, nmp_nconnect, and nmp_nclose. In addition, remote procedure calls (RPCs) to Adaptive Server versions earlier than 12.5 also fail.

Workaround: Use TCP listeners for all Sybase servers, including Adaptive Server, Backup Server, Monitor Server, and XP Server. Alternatively, you can also modify your sql.ini file with an ASCII text editor to remove the named pipes.
