The CA Performance Management (CAPM) CA Performance Center (CAPC) web server UI is returning http 500 errors when attempting to log in. It was previously functioning normally and this error appears suddenly and unexpectedly.
The error continues after restarting the CAPC services.
All supported CA Performance Management releases
The CAPC servers /tmp/ribcache directory is consuming all available space in the /tmp directory.
Note that when the CAPC services start after deleting the /tmp/ribcache, they will download the Data Aggregator RIB documents into /tmp/ribcache.
Initially it will take longer for CAPC to complete RIB calls against the DA.
Once the RIB documents have been fully downloaded, the next restart of CAPC services will allow DA RIB calls sooner since the RIB docs will be in the cache.
