Problem:

RM/InfoExpress displays the error message:

rmdisptcp: 30, RM/InfoExpress Server error 3 (Loc 485)

Resolution:

The 30 error is telling you it’s a non-COBOL permanent error, i.e. not related to the COBOL file system but something else.   The next part tells you what software generated the error, in this case RM/InfoExpress actually generated the error.  The last part, the error code, 3 in this case, is telling you :

Error code 3: RMIX_API_ERR_TOO_MANY_USERS

Failure Definition: Indicates that too many server display programs are being invoked. The
limit is nine for UNIX and Windows.

The solution is to close any unnecessary server display applications.  If in the unlikely event that there aren't any running then a reboot of the machine is required.
