We need to acquire a memory module for es2004 https://racktables.wikimedia.org/index.php?page=object&tab=default&object_id=1393 as one is faulty and out of warranty.
I do not know the exact type and size, @Papaul probably does.
Old description:
2 out of 2 reboots for es2004.codfw.wmnet have resulted on a memory check error for DIMM B2.
The server actually has 64GB of ram, which were usable before rebooting, but due to the error, only 56GB are available:

The server can be rebooted without problem right now (not in production).
Recommended course of action: stop the server, take the memory slot out and blow into it, retest. :-) If that doesn't work, replace slot.
After maintenance: If this is fixed, ensure to run puppet once before restarting MySQL, otherwise, less memory will be available for it, then repool it.
