Troubleshooting
Problem
Symptom
If a user is trying to use the rest API's in high concurrency it can result in 500 response code and failure errors like the following observed in the file /var/log/cmc.out:
"Could not write to a temporary file. (SQL Code: -264, SQL State: IX000) | ISAM error: no free disk space (SQL Code: -131, SQL State: IX000)" AND
SEVERE [T-43520] [com.ibm.apimgmt.exception.APIGenericException$Serializer.serialize] Error(5c66dc16e4b002aa62ef03a8), Http-Code(500)
Cause
The internal database is set up for 125 connections max, and each REST API Call causes a connection to the Database to write. If a combination of internal load on the server and REST API calls exceeds this threshold, REST API calls may fail and errors thrown
