I have access to a Ubuntu Linux node at my institution. The nodes are shared among the group, but typically I am the only person who uses this particular node.
I am running a calculation in parallel on all 8 CPUs on this node. My calculation runs, but when I view the active processes using
top, I see an additional process that says user
man and command
mandb command seems to be running every time I look at
top, and it appears to take up a fairly appreciable amount of CPU power (
6 %CPU) and memory (
2.5 %MEM), according to
When I look around on the internet, it seems that:
mandbis used to initialise or manually update index database caches that are usually maintained by man.
Why, then, does
mandb run all the time on this node? (I don't have this problem on other nodes within my institution's cluster, according to
top on other nodes.) Why would
mandb need to run all the time, since I am not currently looking at manuals?
Is this process likely to be a phantom process that I can safely terminate using
