SYMPTOM(s):
Database is shutdown abnormally with Lock stack underflow 0 error
Lock stack underflow 0
FACT(s) (Environment):
All Supported Operating Systems
Progress/OpenEdge Product Family
CAUSE:
Incorrect database startup configuration. The -n parameter is set lower then the -Mn multiplied by the -Ma parameter.
FIX:
Increase the "-n" parameter to greater then or equal to (Mn * Ma) + all APW's, BIW's, promon sessions, and local connections.
The -n parameter value indicates the maximum number of users that can connect to the database before being denied access. This value includes shared memory connections, remote connections, batch jobs, promon sessions, Progress background processes such as APW's, BIW's,AIW, and PROWDOG.
The -Mn parameter value is the number of maximum remote servers for the database. This parameter value times the -Ma parameter value gives the maximum number of remote connections to the database. The -Ma parameter value is the number of possible clients that can connect to each server. The number of remote client connections must be less then the number of the -n value.
