[HTCondor-users] swap space

[Almudena Montiel <almudena.montiel@xxxxxx>]

Hi

how could I estimate, or as a rule of thumb, the amount of swap space 
for a htcondor instance?

We have around one thousand slots, and the deployment of HTCondor 
central services is simply configured in one physical server. This 
server is IBM 69Y4438 , 1TB SAS3 in RAID6, RAM DDR3 24G and we have 
created a swap space of 24G.

Sometimes we have seen peaks of swap consumption, especially by the 
condor_collector daemon, becoming 100% of used swap space. This lead to 
a problematic situation.

Is this normal? Shall we increase the swap space? Or does this anomaly 
come from other reason?

Cheers
