Re: [HTCondor-users] calc_phys_mem() fails on Xen VMs?

Hi Dennis,

This is a result of HTCondor failing to calculate the available memory or is calculating less than 1 MB of memory. I did some git archeology and did notice that in V23.6.1 we changed the code to do this calculation based on information from Linux cgroups (commit). Did or does HTCondor start up successfully in this environment when using an older version (i.e. V23.5.3)?

Curious error from the StartLog:

09/09/24 12:43:49 Error computing physical memory with calc_phys_mem().
                 MEMORY parameter not defined in config file.
                 Try setting MEMORY to the number of megabytes of RAM.
09/09/24 12:43:49 ERROR "Can't compute physical memory." at line 103 in
file ./src/condor_startd.V6/ResAttributes.cpp

This is Debian 12, Condor 23.6.1-1.1.

Not really sure what may cause this.
