At CentricsIT, we are your IT experts. When any IT maintenance issue arises in your data center we are here to help. If there is an error code you can’t fix, let us assist you in our monthly FixIT column. This month, we’re covering the HP error: MEM_PDT_TABLE_FULL or the PDT Full Memory Error in MP SL Logs.
What is the PDT Full Memory Error in MP SL Logs?
This is a critical level-five error and will present itself commonly during system boot. The error occurs in the page deallocation table (PDT) which is where the system logs all single and multiple bit memory errors. The procedure below will show you how to clear the PDT from the shell prompt which will resolve the error.
Note: The PDT table can be cleared, however it is best to record its contents before clearing. Too many errors on the same DIMM could lead to an unstable system. CentricsIT can check and replace the eventual bad DIMM(s) in order to avoid system crashes in the future.
