Issue:
We are getting multiple TSS9122I messages 6 servers down, 100 users affected.
Environment:
z/os
Cause:
At present there is no way to know if LDAP is flooding the system with list requests.
Resolution:
At present there is no way to know if LDAP is flooding the system with list requests.
I can think of one way to determine if number of list request are high, would be to use the STATG output from a ten minutes interval.
One would check the number of list commands between the end - beginning, then determine if that number is high for your system.
You should also open an ideation request in TSS community about control the number of list commands via LDAP and see what others think.
