APAR status
Closed as program error.
Error description
Applications that query network statistics currently must wait until any other query is completed. Some network devices such as san storage (npiv) can wait many seconds for a target devices to respond and the query to complete. This can result in functions such as uuid_create() which indirectly query network to pause many seconds. This has negative consequences for applications such SAP.
Local fix
If a call to netstat -v stalls before completion then there is exposure to this problem. Remove all unusued/unconfigured npiv devices from the client lpar. Confirm netstat -v does not stall before completion.
Problem summary
uuid_create() may hang for over 2 minutes whenever there is a non responsive npiv adapter(Ex fcs switch is messed up) and they call uuid_create()
Problem conclusion
Ndd lock serialization is fixed.
Temporary fix
